dc.description.abstract As MIMO-OFDM systems gain in popularity and move towards commercialization, the impact of analog hardware impairments need to be addressed to ensure these systems achieve the significant capacity/throughput gains they are capable of. In this paper we discuss the impact of correlated and uncorrelated phase noise on MIMO-OFDM systems. Where transmit (or receive) antennas are not colocated the phase noise is uncorrelated. Even in systems where the antennas at the transmitter/receiver are co-located, the multiple RF chains could have dedicated PLLs which introduce uncorrelated phase noise. We compare the performance degradation due to phase noise and show the impact of correcting phase noise in both these situations. en_AU
