Abstract: A new RM statistical model in the partial shadowed for the land mobile satellite channel is proposed.The received amplitudes were classified into several states according to the degree of shadowed experimented.Partial fading model of received signal proposed is a new combination between the total shadowed and non-shadowed based on the factor A is related to shadowed and other environmental factors.The relationship among the expectations(in dB)of received signals,non-shadowed and total shadowed is linear relation and the expectation of received signals(in dB)is in direct proportion to A.Tuning the factor A is flexible to simulate the received signals.Comparison demonstrates the fading model is valid.
