摘要
本文介绍了卫星通信系统中一种采用数字变频技术的设计及应用,与模拟变频器相比,它对信号在中频进行数字化处理,简化了收发信机前端电路设计,着重讲述了数字变频的原理、算法以及在卫星通信系统中的设计应用。
The paper introduces the design and application of digital frequency conversion in satellite communication system, mainly discusses the theory and algorithm of digital frequency conversion as well as the application in satellite communication system. Compared with analog frequency converter, the digital frequency converter carries digital signal processing in intermediate frequency, which can simplify the front end circuit design of transmitter receivers.
