In this paper we analyzes the performance of MIMO-OFDM systems with independent phase noise at transmit and receive antennas using zero-forcing (ZF) detectors over frequency selective Rayleigh fading channels. Approximation to the distribution of central complex Wishart distribution is used to derive signal-to-interference-plus-noise ratio (SINR) the system. So the bit error rate (BER) of the system can be denoted based on the analysis of the inter-carrier-interference (ICI) due to phase noise. Simulation results illustrate that the theoretical analysis is quite accurate in Rayleigh fading channels.
