Abstract
Consider N-transmit M-receive antenna systems with multiple frequencies and delay spread. Expansions are given for the distribution and quantiles of the channel capacity efficiency C in powers of N?1=2 for fixed M. The first term gives normality. This gives a good approximation for M=N small. For M < N the second or third term is generally sufficient for accuracy. An important duality principle is given: expansions for the distribution and quantiles of C in powers of M?1=2 for fixed N follow. The first term gives a good approximation for N=M small. Both discrete and continuous time models are considered.
