Channel Coding Diversity with Mismatched Decoding Metrics

We analyze the performance of channel coding diversity with general decoding metrics in terms of the generalized mutual information (GMI). We show that the GMI of the diversity channel is less than or equal to the baud-rate weighted sum of the component GMIs; and equality is achieved only in special...
