摘要
K a频段卫星作为未来卫星通信发展的主要频段 ,但其面临的信道衰落是比较严重的 ,因此对信道传播衰落效应进行研究是十分必要的。本文在对 Ka频段卫星通信的信道模型分析的基础上 ,利用分析法导出了相干 BPSK信号在 Ka频段的系统性能 ,并进行仿真 。
Kaband is the main band suited for the future satellite development,which the fading of channel of which is very serious It is essential to make the research of propagation fading effect On the basis of the analysis of channel model for Kaband satellite communication, the analytical derivation of the system performance of coherent BPSK signal at Kaband is described so do the system simulation Finally some useful conclusion is drawn
