Abstract

This paper analyzes the influence of independent identical distributed phase noise (PN) at different transmit and receive antennas on the performance of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based communication systems. Assuming PN is not severe, we can show that the ICI of the phase noises can be separated into two additive terms, which are induced by transmit PN and receive PN, respectively. The ICI caused by transmit PN remains the same in all cases, while the impact of receiver PN depends on specific scenarios: it decreases when the number of receive antennas increases, and is equal to the impact of transmit PN when the number of receive antennas is equal to that of the transmit antennas under optimal LOS condition (unitary channel), or when the number of receive antennas is two times that of transmit antennas under Rayleigh fading.
