利用MATLAB软件,构建Chen-Mbius八路数字通信系统,对5种常用函数族(偶对称方波、奇对称方波、偶对称三角波、奇对称三角波和锯齿波函数族)调制解调系统进行仿真.通过计算机编程运算,对保存的信噪比和错误概率的数据进行处理.结果表明,新系统利用调制的原理,使得原始信号在经过乘法器之后得到的信号的带宽有较大幅度的提高,相当于对原始信号进行了扩频变换. Using Matlab software, the Chen-Mbius eight-channel digital communication system is constructed and the modulation and demodulation systems of five commonly used function families (even symmetrical square wave, odd symmetrical square wave, even symmetrical triangular wave, odd symmetric triangular wave and sawtooth wave function family) Simulation results show that the new system uses the principle of modulation to increase the bandwidth of the signal obtained after the original signal passes through the multiplier. , Equivalent to the original signal spread spectrum transform.
