Evaluation of capacity of indoor MIMO channel with different antennas array

The effect on the capacity of indoor MIMO channel with LOS path caused by the different antenna array structures is analyzed by using a 2-D SBR ray-tracing. The results show different antenna array structures affect the CCDFS greatly in LOS indoor environments and the less antenna spacing is, the mo...

Description
Summary:The effect on the capacity of indoor MIMO channel with LOS path caused by the different antenna array structures is analyzed by using a 2-D SBR ray-tracing. The results show different antenna array structures affect the CCDFS greatly in LOS indoor environments and the less antenna spacing is, the more capacities change of the MIMO channel will be. 10% outage capacities also show there exist a fixed relationship that i.i.d. Rayleigh channel capacity is larger than the capacity equipped with linear antenna array which is larger than the capacity equipped with circular antenna array and the capacity equipped with circular antenna array is larger than the capacity equipped with rectangular antenna array.
