A Unified Performance Analysis of Digital Communication with Dual Selective Combining Diversity over Correlated Rayleigh Fading Channels

Using a simple nite integral representation for the bivari-ate Rayleigh cumulative distribution function recently discovered by the authors, we present expressions for the out-age probability and average error probability performances of a dual selective diversity system with correlated slow Rayleigh fading either in closed form (in particular for binary diierential phase-shift keying) or in terms of a single integral with nite limits and an integrand composed of elementary (exponential and trigonometric) functions. Because of their simple form, these expressions readily allow numerical evaluation for cases of practical interest.
