本文基于MATLAB仿真软件,以二进制数字调制系统为研究对象,对二进制频移键控(2FSK)、幅移键控(2ASK)、相移键控(2PSK)三种调制解调方式进行分析.利用MATLAB中的.m文件建立了2FSK、2ASK、2PSK仿真模型,并对仿真模型进行了测试.结果表明,仿真结果与理论基本一致.
This article is based on the MATLAB simulation software,in binary digital modulation system as the research object,the binary frequency shift keying (2 FSK),amplitude shift keying (ask),phase shift keying (PSK) 2 three modulation demodulation methods are analyzed.Using MATLAB.In the m file set up 2 FSK,2ASK,2 PSK simulation model,and the simulation model was tested.The results show that the simulation results are consistent with theoretical basic.
