It contributes towards the estimation of common phase error term, which is used for the excision of intercarrier interference. The main focus of presented research work is on the effects of phase noise on the performance of underlying OFDM system for the different number of subcarriers in the fixed/same OFDM symbol block period/duration, for the different M-ary PSK modulation techniques, and it emphasizes on the impact of jammer noise, while using zero-forcing (ZF) and minimum-mean-square-error (MMSE) techniques for detection. Simulation results are demonstrated to verify efficacy of the blind-phase-noise-compensation (BPNC) technique under the fading environment.
