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. |
