On the monotonicity of matched-filter bounds for diversity combining receivers

An analytical framework to assess the performance of a given diversity system in wireless environments characterized by their power dispersion profiles is established. In particular, we consider maximal-ratio diversity systems and proved the monotonicity of their matched-filter bound performance. Our results are general in that fading distributions are not required to compare and/or bound the performance of a given diversity system in different wireless environments. Hence, these results are valid for arbitrary fading distributions.
