高速卫星数传并行解调仿真分析

Simulation Analysis of Parallel Demodulation Techniques for High Speed Satellite Data Transmission

针对高速卫星数传链路，在NASA数字高速并行接收机（APRX）基础上，建立了高速并行接收的仿真模型，对并行解调中涉及的整体架构、采样率、并行匹配滤波、锁相环、符号定时与载波同步等关键问题进行了详细说明，建立了仿真模型，为后续软硬件实现给出了理论依据。

A high speed parallel veceiding simulation model is developed for the requirement for high speed sat- ellite data transmission link based on NASA APRX and the detailed design for model framework, sampling rate, parallel matched filter, phase locked loop, and symbol timing and carrier wave synchronization techniques, etc. are made, which provide the theoretical basis for follow-up develop of hardware.
