星地通信中频谱翻转现象分析

The Analysis of Spectrum Inversion in Satellite-ground Communication

卫星数据传输需要进行调制解调和变频处理,通过分析调制和变频等环节造成的频谱翻转的机理,提出解决频谱翻转的方法,对星地数传系统设计及联试具备重要参考作用.

Satellite data transmission requires modulation and demodulation and frequency conversion.To analyze the mechanism of spectrum inversion caused by modulation and frequency conversion,A method to solve spectrum inversion is proposed,It is an important reference for the design and test of satellite and earth data transmission system.
