Abstract:
A channel model to the land mobile satellite communications is described,in which two independent Log-normal random processes effected on the LOS signal and the multipath signals,respectively.The received signal is the sum of two components,the Lognormal component and the other component,which is the product of the Rayleigh and the second Lognormal.The second order statistic characteristics,level cross ratio and average fading duration,of the model are derived.The consistence of the simulation and the analytical results is showed by the figures.
