摘　　要：本文给出了卫星通信系统设计、建模和仿真的一般方法 ,重点是Ka频段卫星通信信道的建模及仿真。我们首先分析了Ka频段卫星通信信道的统计特性 ,建立了信道的统计模型 ,然后在此基础上建立了Ka频段卫星通信信道及系统的仿真模型 ,并进行了系统性能的仿真 ,最后利用分析法分析推导了相干BPSK信号在Ka频段的系统性能 ,并与仿真结果进行了比较 。This paper presents a general method for satellite communication system design,modelling and simulation.Stress is placed on modelling and simulation of a Ka band satellite communication channel.Statistical characteristics and model of the channel at Ka band are given firstly,then we conducted the system performance simulations based on the channel and system simulation model proposed by this paper.Finally the analytical derivation of the performance of coherent BPSK signal at Ka band is described and a useful conclusion is drawn by comparing with the simulation results.
