Abstract
AbstractAn analysis for the Shannon channel capacity of dual‐branch selection diversity receivers operating over correlative Weibull fading is presented under three adaptive policies: constant power with optimal rate adaptation, optimal power and rate adaptation and channel inversion with fixed rate. In this context, useful formulae for the average channel capacity with not necessarily identical fading statistics and arbitrary parameters for both the correlation coefficient and fading severity are derived in closed form. The analysis also includes the performance of single‐branch receivers where special cases of the expressions agree with known results. Illustrative numerical examples are also presented, demonstrating the effects of the correlation coefficient, fading severity and signal‐to‐noise ratio unbalance on the receiver's performance.
