Performance evaluation of 64-ary QAM OFDM system in terms of ser calculation and throughput measurement for AWGN channel

In this paper, the performance analysis of 64 QAM-OFDM wireless communication systems affected by AWGN in terms of Symbol Error Rate and Throughput is addressed. 64 QAM (64-ary Quadrature Amplitude Modulation) is the one of the effective digital modulation technique as it is more power efficient for larger values of M. The MATLAB script based model of the 64 QAM-OFDM systems with normal AWGN channel is made for study of error performance and throughput under different channel conditions. This simulated model maximizes the system throughput in the presence of narrowband interference, while guaranteeing a SER below a predefined threshold. Lastly comparative study of SER performance of 64 QAM-OFDM simulated & 64 QAM-OFDM theoretical under AWGN channel is given.
