Abstract :
We present a unified study on the output MAI Gaussianity for progressively more complicated systems. We first generalize the results of Zhang, Chong and Tse (see IEEE Transactions on Information Theory, 2001) to the complex signature case, and establish the output MAI Gaussianity. Then we extend the study to systems with MMSE receivers and antenna arrays, and establish the joint Gaussianity of the output interference across the the antennas
