Abstract:Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier transmission technique in which single data with higher rate is partitioned into multiple lower rate data streams to exhibit the parallelism and orthogonality. Modulation technique is one of the important hand tools in OFDM based wireless communication system. In order to improve the OFDM based wireless communication system, it is better to design an efficient modulation technique for achieving efficient Area, Delay, and Power. Thus different types of modulation techniques such Quadrature Amplitude Modulation (QAM), Quadrature Phase Shift Keying (QPSK) modulation; Binary Phase Shift Keying (BPSK) modulation and M-ary PSK for different bits are proposed in this project. In order to reduce the AWGN noises in OFDM signal, an efficient encoders and decoder such as Hamming encoder and hamming decoder are proposed in this project. Performance measurement of this project is analyzed in terms of Lower power consumption, high speed and less area utilization..
