基于信号仿真的通信信号环境构设方法

针对目前通信信号环境构设方法在便捷性、经济性方面的不足,提出采用信号仿真的通信信号环境构设方法.以超短波通信工作为例,介绍通信信号环境仿真流程,引入复数包络方法,划分仿真功能模块、明确模块间的输入输出数据,给出采用Simulink工具箱构设典型语音调频通信信号环境的实例.结果表明:该方法是可行、有效的,能仿真通信信号的产生、发射、传播、接收、滤波和解调的全过程.

Construction Method of Communication Environment Based on Signal Simulation

Aiming at the defects of convenience and economics to construction method of communication environment, introduce communication signal environment construction method by using signal simulation. Taking ultrashort wave communication as example, introduce communication environment simulation progress, use complex envelope method to divide simulation function module, ensure input and output data among modules, and give example of typical voice communication signal environment of based on Simulink tool box. The results show that the method is feasible and effective. It can simulate whole process of communication signal creation, emission, transition, receiving, filtering and demodulation.
