Abstract

The study of the capacity bounds for the K-user multiple access channel (MAC), reveals that certain random matrix theory results are of practical relevance to the problem. The result form the point-to-point block Rayleigh fading channel indicate that isotorpically distibuted input signals are capacity achieving in the high-SNR regime. The derivation of the mutual information obtained with these input signals in the MAC case requires analysis of the eigenvalues of certain Gramm matrices, with rows which are random vectors uniformly distributed on a unit sphere.
