Abstract-Exact expressions for the level crossing rate and average fade duration of M -branch equal-gain and maximalratio combining systems in a Hoyt fading environment are presented. The expressions apply to unbalanced, non-identical, independent diversity channels and have been validated by specializing the general results to some particular cases whose solutions are known and, more generally, by means of simulation.

Abstract-This paper derives exact expressions for the level crossing rate and average fade duration of equal-gain and maximal-ratio combiners for the α − μ (Generalized Gamma) fading Distribution, assuming M unbalanced, non-identical, independent diversity channels. The analytical results are thoroughly validated by reducing the general case to some particular cases (Nakagami-m and Weibull), for which the solutions are known, and by means of simulation, for the more general case. In addition, several new closed-form expressions are also obtained for other special cases.

ABSTRACT-Radio-wave propagation through wireless channel is a complicated phenomenon characterized by fading which is the result of multipath propagation. In wireless communication system, random process associated with fading channels can usually characterized by their PDF (Probability Density Function) and CDF (Cumulative Distribution Function). Signal fading can drastically affect the performance of terrestrial communication systems. Several statistical models are available for describing the fading envelope of the received signal in which Rayleigh, Rician and Nakagami are the most frequently applied models. Higher-order statistics such as Level Crossing Rate (LCR) & Average Fade Duration render (AFD) insight into signals which is not always available at lower orders.
