This is an early study of the capacity of MIMO channels inspired by the work of Telatar and Foschini. It shows that the capacity grows linearly in the number of transmit and receive antennas (degrees of freedom) either when the SNR becomes large or when the number of antennas in the MIMO system becomes large. It shows that the linear rate growth can be achieved by simpler linear detector structures, such as a matched filter receiver. However, it shows that the price paid for simple matched filter receivers is that the SNR growth flattens. It also examines the case where the channel matrix has a constant expected Frobenius norm. In this case, even with isotropic fading, it is shown that the capacity of MIMO channels does not grow linear in the number of antennas, but grows linearly in SNR. Finally, the effect of time-variation within a transmission block for ISI fading channels is examined in terms of capacity.
