This article commenced the real-time education and research podium for characterize wireless networks, analog and digital communications courses with National Instruments Universal Software Radio Peripheral Device (NI USRP 2901) device. The 5G Cellular communications will claim remarkable flexibility from the physical layer. Many research ideas are proposed and compared with the theoretical part but there is a lack of enactment of a system under real-time channel conditions and front-end impairments. In this article, a single-input single-output generalized frequency division multiplexing transceiver is performed with NI USRP 2901, which utilizes radio frequency platform it has the ability to work as the transceiver in the frequency range of 70 MHz to 6 GHz and it also provides multiple input and multiple output support, which is helpful for the implementation of industry-based wireless operation prototypes. The generalized frequency division multiplexing system model is programmed in the LabVIEW software block diagram panel along with USRP configuration utility. In view of field-programmable gate arrays, both programming host handling and continuous preparing can be actualized. This usage enables the clients to assess distinctive generalized frequency division multiplexing performance characteristics, such as total harmonic distortion, signal in noise and distortion (dB), and specific harmonic, transmitted bit stream and received bit stream with error count, bit error rate value, and its graph are plotted. The simulation results show that the generated generalized frequency division multiplexing signal has a total harmonic distortion value of 0.793054 and signal in noise and distortion value of 0.204343. The specific harmonic value is 0.0228768 and the bit error rate value is 0.003125. The generalized frequency division multiplexing signal slightly outperforms the orthogonal frequency division multiplexing signal in terms of real-time transmission signal characteristics such as total harmonic distortion, signal in noise and distortion, bit error rate, power spectrum value, Wigner–Ville distribution value in the two-dimensional array and corresponding graphs are plotted. The proposed system outperforms existing system by a margin of 3% in real-time channel using the USRP 2901 device. [ABSTRACT FROM AUTHOR]

Recent breakthroughs lowering the costs of software-defined radio devices have made them very attractive for teaching wireless communication. This paper provides an example of an undergraduate course that incorporates the use of low-cost software-defined radio and Matlab/Simulink software to illustrate the basic principles of practical digital communication systems. This course targets senior level undergraduate electrical engineering students with a background in the fields of communication and signal processing. The course comprises two parts: software-defined radio introductory studies and implementation of a basic digital modem. The second part of this course may also be taught as project-based learning or in a hackathon-style event. Finally, a list of additional project-based learning/hackathon projects is provided.

A matched filter is an essential element in digital communications receivers. It is known that it is optimal, in the sense of producing sufficient statistics of maximum signal-to-noise ratio; a proof is presented in many undergraduate textbooks. Recent research in mathematics education suggests that the purpose of a proof is not merely to convince students that a theorem is true by pure logic; rather, a proof should be explanatory, with semantic content that elucidates the relationship between the concepts involved. In this paper, a time-domain proof that the matched filter is optimal is presented, and it is argued that it has larger explanatory value than alternative proofs. [ABSTRACT FROM AUTHOR]

In telecommunications engineering degrees, simulations are used to understand better theoretical concepts. However, in courses related to digital communications or signal processing usually these simulations cannot be easily applied to real data or in real scenarios. This limitation does not allow the students to verify that the learned theoretical hypotheses are valid in practice. Nowadays, software defined radio platforms have been proposed to validate theoretical telecommunications concepts in real situations. Therefore, by combining a software defined radio and simulation tools, students can implement the learned notions over real data in real scenarios. This allows students to work under real applications in order to learn by experience and to see that the theoretical concepts are valid in the real world. This paper presents a project involving real-time decoding of automatic dependent surveillance–broadcast (ADS-B) signals, implemented by using a universal software radio peripheral software defined radio and MATLAB®. The universal software radio peripheral allows to receive real automatic dependent surveillance–broadcast signals sent by the aircraft. Then, by using MATLAB® tools, the automatic dependent surveillance–broadcast baseband signals are decoded. The students are guided through a manual to demodulate the real automatic dependent surveillance–broadcast signals and display in a map the aircraft trajectories. The evaluation is based on a competition between the students, considering execution time of their algorithms, and a final report of the project. This project allows to obtain a game-oriented and novel approach for teaching digital communications and signal processing. The implementation of this project in telecommunications engineering courses motivate the students, allowing them to understand better difficult theoretical concepts, and improve their computer, teamwork, and collaboration skills. The originality of the approach is based on the usage of a prototyping platform, combined with simulation tools, for practical application of telecommunications engineering concepts using real signals.

Polyphase filter design is a common subject studied in discrete systems analysis and digital signal processing (DSP) courses. However, the classic z -domain analysis, utilizing the noble identities, gives a conclusion to the true physical structures of polyphase filters which may not be obvious to many students. The proposed time-domain analysis provides a more straightforward development of polyphase implementation of interpolation and decimation functions, and hopes to provide students with a more visual representation of the polyphase interpolation and decimation processes. Results from a student survey show that over 73% of students believe that the proposed polyphase analysis strengthened their understanding of polyphase filters, and over 71% would prefer to use the proposed method over the traditional z -domain analysis when explaining polyphase filters to others.

This paper presents the development of Electronic Circuits, an elective course in the final year of computer and digital system engineering Bachelor programmes at Chalmers University of Technology. Serving as a bridge between the traditional circuits perspective of junior-level courses and the electronic system perspective of senior-level courses, the course was developed to lay a foundation for contemporary electronic system design in a manner that spurs student motivation. The course adopts an integrated view of analog circuits, digital circuits, and wires, and this necessitates a new pedagogical flow, including an extensive set of design-oriented exercises.

The work reported in this paper serves two purposes. First, an alternative comprehensive approach is proposed for the understanding of the mechanism behind QPSK. This focuses on how a QPSK modulator decides to represent each pair of bits to be transmitted, by which of its four possible phase shifts. This approach is based entirely on the analysis of phasors and is completely mathematicsless. The second part of this work proposes a method by which complex modulation schemes, like QPSK, can be implemented using only first degree components in Simulink, avoiding all the hurdles of mathematically complicated blocks. The implementation, in the second part, confirms the viability of the approach in the first part of this work. Results show that the data received on the other end of a noiseless channel exactly matches the data sent despite a slight unavoidable delay. The proposed method for implementing QPSK can be used directly as a laboratory exercise for undergraduate students new to digital communication techniques. [ABSTRACT FROM AUTHOR]

This paper presents a digital signal processing laboratory developed for analysis of voltage events in power systems. The designed laboratory permits the analysis of simulated voltage events of different magnitude, duration and point-on-the-wave of beginning as well as the analysis of real voltage events from records taken by power quality monitoring equipment, using different signal processing tools such as r.m.s magnitude, Fourier analysis, Kalman filtering and wavelet analysis. This laboratory has been used as a benchmark in the development of new signal processing methods for the complete characterization of voltage events in power systems as well as a powerful teaching tool in electrical power quality courses.

There has been an increasing use of modern digital signal processors (DSPs) in industrial control and other applications in the past few years. While courses offered in electrical and computer engineering disciplines cover such topics as mobile and digital communication, image and sound encoding and decoding, few courses focus on the use of DSPs in real-time control of electrical machinery and drives. Therefore, there is a growing need in industry for engineers who can perform control design and system integration for various applications in motor control. This paper describes a course on Control of Electrical Machines offered by the School of Industrial Engineering of Barcelona (ETSEIB), Polytechnic University of Catalonia (UPC), Barcelona, Spain. A description of a hands-on laboratory testbed for motor control. An outline of the course structure, the laboratory setup and the design aspects for implementing modern real-time motor control applications are presented. [ABSTRACT FROM AUTHOR]

In this paper a unified framework for presenting various entropy quantities needed in information theory is given. This method allows an easy, elegant and compact presentation and lends itself to easy implementation using standard mathematical/engineering software. Examples illustrating the use of this technique are given together with a general MATLAB program for calculating entropies as well as the channel capacity. The technique was preferred over classical representations by undergraduate students taking a first course on digital communications. [ABSTRACT FROM AUTHOR]

A web-based on-line framework has been created to augment an undergraduate course in communication theory aimed at Spanish telecommunication engineering students. Its aim is to enrich the students' understanding on basic topics such as analogue and digital communication systems, information theory, random signals and noise, as well as to provide remote support, additional information and interactive tools. As an ultimate goal, it tries to contribute to a redefinition of the role of the student as the principal actor of his or her own learning. [ABSTRACT FROM AUTHOR]
