Channel capacity with channel interference in MIMO-WLAN systems

The channel capacity of multiple-input multiple-output (MIMO) wireless local area network (MIMO-WLAN) systems with co-channel interference (CCI) is calculated in this paper. The ability to combat CCI for the MIMO-WLAN simple uniform linear array (ULA) and polarization diversity array (PDA) are investigated. The channel frequency response, which is further used to calculate the corresponding channel capacity is calculated by ray-tracing approach. Numerical results show that MIMO-PDA is better than those of MIMO-ULA when interference is present.
