摘要

提供了一种卫星数传通信系统运行仿真平台的设计方法。首先利用带通采样定理，对仿真系统进行了采样率设计，总结了最低等效载波频率的计算公式，可直接应用该公式进行设计，同时进行了与实际系统时间和频率的等效设计；其次根据系统的功能结构，设计了系统软件架构和运行进程；最后根据需要建立了相应的功能模型。该卫星数传通信仿真系统包括独立运行和网络调度运行两种工作模式，能够仿真包括射频调制在内的发射和接收所要求的功能模型，并提供分析评估模型。通过分析评估模型，给出了整体仿真系统的频谱、眼图、误码率与信噪比的情况，通过分析，仿真的结果与理论是相吻合的。

Abstract

A design method of data traffic satellite system has been developed. Firstly through band-pass sample theorem

the simulation system sample rate has been designed and furthermore the lowest equivalent carrier wave formula was deduced

the deduced formula is able to be applied into other simulation system. At the same time

the equivalent design methods to the practical system time and frequency spectrum were presented. Secondly according to the system function structure

the system software frame and running threads was studied. Finally corresponding function models has been realized. Two work modes including independent running and network controlling were provided

functional models

which were required by the transmitter and receiver of data-traffic satellite system and including radio modulation

were simulated integrally. Based on the evaluation model

the frequency spectrum

eye pattern and relation of BER and SNR are presented

and the simulation results are in agreement with theoretical values.
