OQAM based Bi-orthogonal 5G System for IoT Device Communications

The recent advances in wireless technologies made it possible to inter connect every device wirelessly to the Internet, which is called as Internet of Things (IoT). 5G cellular communication research community has been compelled to design solutions for the IoT along with conventional data communications and voice/video over IP networks. The IoT plays a critical role in the modern society with smart cities, smart power grids and other applications. These applications demand ultra low power and low cost solutions. To meet such diversified requirements, novel physical layer need to be designed. In this paper, a novel accessing technique with the LTE procedures defined by 3GPP has been used to cater the needs of IoT devices generated random traffic. A new system with Offset Quadrature Amplitude Modulation (OQAM) and bi-orthogonal frequency division multiplexing (BFDM) is simulated using Matlab Software along with BFDM QAM and LTE based OFDM. In this paper, the performance of BFDM-OQAM system is compared with OFDM and BFDM QAM systems under Line of Sight fading conditions such as Rural Line of Sight (RLOS), Highway Line of Sight (HLOS), and Urban Approaching Line Of Sight (UALOS).
