【摘要】 阐述了皮卫星通信系统中解词模块的实现方案,详细介绍了基于DSP的数字解调的基本原理和具体结构、仿真情况、实测结果以及误码率的测试平台。验证了星上解词系统由模拟走向数字的必然性。
【Abstract】 It describes the principle and realization of demodulation module in pico-satellite communication system. The detailed discussion is provided in the structure of demodulation scheme based on DSP circuit. The analysis in the simulation result and BER testing method are also presented. As a result, the analog demodulation system in satellite must be taken place by the digital system.
