  • 摘要:As more and more people started using the communication equipments, the demand for high data rate increases quickly.Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest modulation techniques used in order to combat the frequencyselectivityof the transmission channels, also achieves high data rate without inter-symbol interference. The basic principle of OFDM isgaining a wide spread popularity within the wireless transmission community. This paper deals with the communication system that usesBPSK, QPSK and QAM techniques to transmit information using OFDM technique over Rayleigh communication channel. In terms ofSymbol Error Rate (SER), the performance of different modulation schemes using OFDM techniques in Rayleigh channel is analyzed. Fordifferent types of modulation schemes (BPSK, QPSK, 16-QAM, 64-QAM) has been used with OFDM techniques. In this paper we analyzethe Bit Error Rate (BER) of Rayleigh Fading Channels in OFDM systems using BPSK, QPSK and QAM Modulation Schemes
