| Abstract: | The deterministic simulation models for land mobile satellite communication channel are established basing on the approximation of Gaussian color process applying finite sums of weighted harmonic signals, and the determining parameters method of simulation models is obtained. The results by comparing the autocorrelation functions of simulation model and theory model illustrates that the model is feasible. The proposed models get over the sample frequency and bandwidth limitation of conventional matching filter. Furthermore the probability density function when the amounts of harmonic signals are infinite, and bit error probability function are derived. |
