Abstract: In order to make channel model reflect real channel propagation characteristics more accurately, an extended Suzuki model with double-end truncated power spectral density for land mobile satellite channel was proposed according to the distribution characteristic of Doppler spread power spectral density in frequency domain. It was assumed in the model that, the power spectral density of the received signal was truncated in the low and high frequency region. The probability density function and level crossing rate of the model were derived, and compared with the experimental data. The simulation results indicate that the model can fit the experimental data better, reflect real channel propagation characteristics more accurately compared with the single side truncated model. It can be converted to other narrow-band satellite channel models when some parameters are given, and the model has a wide range of applicability.
