Abstract

5G NR (New Radio) incorporates concepts of novel technologies such as spectrum sharing, D2D communication, UDN, and massive MIMO. However, providing security and identifying the security threats to these technologies occupies the prime concern. This paper intends to provide an ample survey of security issues and their countermeasures encompassed in the technologies of 5G NR. Further, security concerns of each technology are defined mathematically. Thereby defining the impact on the factors of security. Moreover, a methodology is developed in which the influence on security due to artificially generated rain and artificially generated dust on the wireless communication network is studied. By doing so, an attacking scenario is identified, where a half-duplex attack in D2D communication is attained. Half-duplex attack specifies the attack solely on the downlink to spoof the allocated resources, with reduced miss-rate. Thus, ultra-reliable and adequate advances are required to be addressed to remove the obstacles that create a hindrance in achieving the secured and authenticated communicating network

Abstract

Now days, free space optics (FSO) is one of the emerging technologies in the field of communication which has seen gigantic interest and vast evolution among the researchers. It can be seen as the replacement for the conventional radio frequency communication due to its various advantages of unlicensed band, security, speed as well as the bandwidth. In order to receive high bandwidth it has emerged as a promising technology in today's era. As in case of FSO transmission is done by using optical sources i.e. laser but rather than enclosing data into fibre cable the signal is transmitted via air. In this paper, we mainly contribute towards the general architecture of free space optics network. How data gets transmitted from one point to another while undergoing various attenuation and degradation in the signal because of atmospheric hindrances like snow, rain, fog etc. The main consideration in this paper is towards the high data rate requirement towards the end users.

Author

Singh, Gyanesh and Sabraj, Manish

Abstract

The aim of this proposed work is to designing solar charging controller which is very useful in terms of total charge control and active power of solar pv array to reduce the waste of energy. Also for batter cycle control a suitable electrical control panel is designed. to regulate active as well as reactive power and to regulate the path and time interval of the active as well as reactive power from the sun light of power to the storage system. Some of the other aim of this system is to maintain the reliability of power supply to the consumer weather it is industrial, agricultural, commercial and domestic that must be achieved throughout this proposed work. Provide electronic devices that can solve the problem of power management of solar panels. Simulates a diagram of a photovoltaic charging controller. To achieve accurate results according to the test. Overcharging of 12 volts battery to reduce device quality as well as maintenance and extend battery life.

Abstract

Equalization is a most widely used optimization scheme to reduce inter-symbol interference (ISI).Intersymbol interfering environment is a case of misrepresentation of the sent signal at the receiver. Different symbols can hinder with one another which results innoise and less relevant, reliable signal. Multipath propagation means a wireless signal from a spreader reaches the receiver through numerous paths. If inter symbol interfering occurs within an arrangement, it must be reduced to the most minimal quantity conceivable. The inter symbol interference is reduced through the use of adaptive algorithms; LMS (Least Mean Square Error) and RLS (Recursive Least Square) equalization procedures being the most prominent ones. In this work, a joint adaptive algorithm is proposed and simulated. A novel method involving both LMS and RLS is used for suppression of Inter symbol interference. The LMS has the benefit of a fast convergence rate but has a significant value of mean square error (MSE). However, the RLS complements it with low value of MSE and a slow convergence rate . Thus, a joint RLS and LMS is proposed The proposed method results in improved BER performance, lesser mean square error and a faster convergence. [ABSTRACT FROM AUTHOR]
