Abstract :
A closed form expression for the Shannon capacity of the random signature (RS) multiple-input multiple-output (MIMO) fading channel with mutual interference is found. It is shown that the capacity of a RS-MIMO fading channel is equal to the Shannon capacity of the orthogonal Gaussian channel with no interference if the dimensionality of the received signal is large
