基于UHF卫星通信的调制方案研究
Research on Modulation Scheme for UHF-band Satellite Communication
摘要
UHF频段信号具有穿透能力强、传播损耗小、天线波束宽不需要跟踪、设备体积小、成本低等特点,特别适合于卫星通信。本文通过对多种调制方式的频谱特性、误码率、抗非线性、抗干扰特性和实现复杂度等方面的性能进行分析对比,最后得到一种适合UHF卫星通信的调制方案。
Abstract
The UHF band is suitable to satellite communication due to many characteristics： good penetrability, little path loss, wide-beam antenna and simple etc. Through muhi-analysis of different modulation modes, a proper modulation scheme for UHF-band Satellite
