The Multiple Input Multiple Output (MIMO) systems offer increased capacity by forming orthogonal spatial channels. In practice, however, channel correlation reduces the achievable maximum capacity. In this paper, a new approach is introduced to decrease spatial correlation between channels and increase the maximum achievable capacity. The ray tracing is used to find channel characteristics. The initial results show this approach can provide more than 90% of theoretical limit.
