Abstract
A supremum to the Shannon capacity of a Rayleigh fading channel without side information (SI) is computed using variational methods and is shown to be asymptotically achievable for signal-to-noise ratios (SNRs) approaching either zero or infinity. A lower bound is obtained from the mutual information corresponding to a specific discrete input distribution.Keywords
