Abstract:
In the paper, the Bit Error Rate (BER) performance for variation of Quadrature Amplitude Modulation (QAM) techniques and Guard Interval-Less (GI-Less) OFDM over Rayleigh fading are compared and analysed. In addition the simulations of OFDM signals are implemented with Rayleigh faded signals to investigate the effect of channel fading and to obtain optimum value of BER and Signal to noise ratio (SNR) by applying Zero-Forcing (ZF) and Maximum Mean Square Error (MMSE) techniques. The simulation results achieved BER performance of 10"3 at SNR of 25dB.
