Abstract : Orthogonal Frequency Division Multiplexing (OFDM) is one of the core advancements in the area of wireless communication, where the message is transmitted with the help of orthogonal sub-carriers. In this study, an OFDM system is implemented using 32-QAM symbol mapping. Further, a comparative study is carried out using three different symbol detection techniques, viz. Maximum likelihood, minimum mean square error, and zero-forcing. The channel models adopted here includes both AWGN and rayleigh fading. MSE and BER are the quantitative measures for performance comparison. The simulation results show that MMSE outperforms the other two techniques.
