Abstract

We study the sum-rate of the non-coherent, block Rayleigh fading MAC, with K single-antenna users and a receiver which employs N>=K antennas. We derive the mutual information I (x_1, ... , x_K; Y) with independent unitary isotropically distributed (i. d.) input signals, a setup motivated by the capacity analysis of point-to-point MIMO channels. The results are derived in a semi-analytical form and are valid in the whole SNR region (not only the high-SNR regime).
