摘要
介绍了绕月探测工程数据接收地面站使用的通用解调处理机的基本组成和工作原理;讨论了针对误码率、极化合成、帧同步和滑步容错等指标要求的测试原理和方法,并对其测试结果进行了分析。为卫星通信的基带设备的测试提供了参考。
The basic construction and essential theories of general demodulating processor used in the Lunar Project in China are introduced in this paper. Also, for some important design targets, such as the bit error rate, combination of polarization, fault tolerance for the synchronization and the length error of frames, the relevant test theories and methods are discussed, and the obtained results are analyzed. Our work offers a reference for the acceptance of base-band equipments in satellite communications.
