Authors present a general channel capacity model for a random A.W.G.N. channel in the presence of spatially correlated interference. They consider the case where the channel is random, and full rank and the number of receive elements is allowed to increase indefinitely within a given volume. Authors show that capacity of the channel does not increase indenitely for densely packed elements. Moreover, the limit is governed by the correlation properties of the noise and the channel and as such, a power constraint on the receive elements is unnecessary. They examine two cases: the i.i.d. noise case and the spatially correlated noise case and show that bounds exist on the capacity in each case. Monte Carlo simulations are used to verify the results.
