Existing works on MIMO channel capacity assume that the channel power scales quadratically with antenna dimensions. In a recent work, we introduced a framework for sub-quadratic channel power scaling to model physical MIMO channels, and studied a family of channels with different spatial distributions of channel power. In particular, we introduced the notion of a beamforming channel, realizable in practice via the use of reconfigurable antenna arrays, that yields the highest capacity and… CONTINUE READING
