WLC33-5: Second Order Statistics of Non-identical Nakagami Fading Channels with Maximal-Ratio Combining

In this paper, second order statistical parameters at the maximum ratio combining output of two independent but not necessarily identically distributed Nakagami-m channels are studied. Specifically, generalized expressions of level crossing rate and average fade duration of the combined received envelope are derived. Sample simulation results are presented to verify the correctness of the derived expressions. In addition, numerical results given to demonstrate the behavior of the combined received envelope.
