Abstract
In recent time OFDM uses as a Transmission technique in Mobile radio communication like 3G, Multimedia and Voice transmission. Due to its many advantage, OFDM has become the modern choices for these system. OFDM use multicarrier to transmit data symbol. OFDM divide the high data rate frame into multiple low data rate frame. As we know that low data rate frame has higher symbol period. This enables OFDM to reduce the effect of multipath, impulse noise etc to a great extend. Whereas single carrier system does not have capability to reduce multipath effect. This Paper describe the study and investigate the performance of OFDM system under different channel models like AWGN, Multipath, Rician. Effect has been also taken to provide BER calculation for different modulation scheme such as BPSK, QPSK and 16PSK. To get the standard BER (10-3) analysis, the simulation has been carried out, gives the minimum power requirement for particular modulation technique with a suitable data rate.
