Abstract :
Weibull MIMO channels are difficult to analyze due to their non-linear characteristic. While phase is not a major factor in SISO systems, the analysis of Weibull MIMO systems cannot easily discard it. The capacity upper bound in this work includes the contributions of both envelope and phase through the application of first and second moments of channel matrix elements. The capacity bound allow us to study fading severity as gain or loss of bits. Numerical results confirm the effectiveness of the approach and present a comparison of information rates between Weibull and Rayleigh distributions.
