%X The Joint Probability Density Function (JPDF) of signal envelope and its derivative, which is subjected to composite fading, is analyzed by means of conditional probability density. New uniform expressions for the average Level Crossing Rate (LCR) and Average Fade Duration (AFD) of signal envelope are derived using the above obtained JPDF, then some results of the PDF, Cumulative Distribution Function (CDF), average LCR and AFD of signal envelopes, characterized by Rayleigh-Lognormal, Ricean-Lognormal, Nakagami-Lognormal fading models, are derived via Gauss-Hermite quadrature. Simulation results validate the correctness of these expressions.
