STUDY AND SIMULATION OF THE EFFECT OF THE WAVEFORM (FBMC) ON THE INTERFERENCE BETWEEN CELLS AT MULTIPLE LINKS IN THE NEW RADIO SYSTEM COMPARED TO THE WAVEFORM (CP-OFDM)

Abstract

With the increasing development of smart devices and mobile phones in recent years, the demand for high transmission rates for wireless communication systems, especially cellular communication systems, has increased. And as we know that in order to raise the rates of information transmission in cellular systems, more spectral sources must be used, which in turn led to the widening of the transmission packet width for these systems. For this reason, the multi-carrier technology is a solution to the frequency selectivity problem that single-carrier modulation suffers from. In this paper, a MATLAB-based wireless and cellular network simulation tool and the use of object-oriented programming methods are used to study and simulate intercellular interference at multiple links in a new radio (5th generation) mobile phone system. Where the study was conducted by comparing two types of waveforms (CP-OFDM) and (FBMC), through both throughput, Bit Error Rate (BER), as well as the frame error rate (FER). The results obtained from the simulation showed that the waveform (FBMC) could be a more effective solution. It increases the throughput rate and reduces the bit error rate and frame error rate for the primary user compared to the OFDM waveform
