In this paper, we investigate the phase noise properties and the impacts caused by phase noise on an OFDM system, we derive the approximate expressions for BER performance in AWGN channel with various modulations techniques. The performance degradation is analyzed by graphs of BER against the number of sub-carriers. Thus the choice of the number of sub-carriers involves a tradeoff between mitigation of multi-path delay spread and reducing phase noise effects. Simulation results also show that phase noise effects performance for BPSK, QPSK & 16PSK constellation which lead to the conclusion that a phase noise mitigation mechanism is needed to obtain acceptable performance.
