摘要
总结了W频段卫星通信系统的研究工作。介绍了W频段卫星通信的概念、特点,重点介绍了DAVID,WAVE等W频段卫星通信研究任务,并对研究中现存的雨衰、非线性失真、相位噪声等难点问题及其相关解决方法进行了探讨,最后指出W频段卫星通信任务、信道传输、硬件等方面的未来研究方向。
The review summarizes the research work of the W-band satellite communication system. The concept and the characteristics of the W-band satellite communications are introduced. Especially the recent W-band satellite communications research tasks are introduced, such as DAVID, WAVE and so on, and the existing difficulties is discussed, including rain attenuation, non -linear distortion and phase noise, and their solutions of the study in this paper. Finally, it provides to look forward to the future research direction of the W-band satellite communications missions, channel propagation and hardware.
