Outage probability of multi-cellular MIMO systems in Rayleigh fading

We analyze the performance of multi-cellular MIMO systems in Rayleigh fading. Consistent with practical scenarios, we assume two types of interference: intracell interference from users within the same cell as the desired user and intercell interference from users in other cells. We derive a compact closed form expression for the outage probability of such a system in the form of finite sums. The expression is easily computable and allows for a simpler and faster study of various MIMO configurations. An interesting outcome of the analysis is that using multiple antennas on the receiver side results in better performance since transmit diversity does not combat interference from same cell users.
