  • A 2-D shooting-and-bouncing ray-tracing (SBR) method is used to analyze the different antenna array structures effect on the capacity CCDF of indoor NLOS MIMO channel. The results show in NLOS indoor environments the less antenna interval is, the less MIMO channel capacities get. The results on 10% outage capacity show that there exist a fixed relationship that i.i.d Rayleigh channel capacity is larger than the capacity with linear antenna array which is larger than the capacity with rectangular antenna array or with circular antenna array. When antenna interval is equal to or larger than 3, antennas array structures affect the CCDF indistinctively and all the CCDF approach the theoretical i.i.d Rayleigh capacity, i.e. Telatar capacity. When antenna interval is equal to or less than 1, the CCDFS of MIMO system equipped with different antenna array structures changes remarkably. To obtain the MIMO capacity gains in indoor NLOS environment, antenna interval and antenna structure should be considered jointly when designing the antenna array.
