【Abstract】 This paper derives an expression of MIMO systems capacity with co-channel interference in Ricean-fading,analyses the results using Monte Carlo simulation.The research shows: when there are many interferers in the MIMO systems,given the fixed number of total antennas and under the same fading conditions,it is preferable to allocate the number of antennas uniformly between the transmitter and the receiver for an optimum performance;SIMO systems often outperform the MISO systems,but SIMO systems’ performance will decrease significantly with the increased number of interferers.更多还原
