摘要
本文在分析几种星上处理技术性能和发展的基础上，讨论了它们在卫星移动通信中的应用及实现方法，分析了再生转发器的性能。最后讨论了采用ＤＳＰ芯片实现ＤＱＰＳＫ数字调制信号再生处理的方案，给出了框图。
In this paper,the features and development of several on-board processing techniques are analysed.Based on this,the application and implementation of on-board processing in satellite mobile communications are discussed. In addition,the performance of regenerative processor is analysed.Finally, the plan of implementing DQPSK digital modulation signal regeneration through adopting DSP chip is discussed and diagrams are given.
