产生一段随机四进制信号，对其进行QAM调制后，送入加性高斯白噪声信道传输，用加法运算在已调信号叠加白噪声，模拟加性高斯白噪声信道对信号传输的影响，在接收端对信号进行相应解调，并与原始信号比较计算误码率。改变误差白噪声的功率，绘制信噪比与误码率曲线。并与同组其他同学的性能曲线比较各种调制方式的性能优劣。-For some randomly generated four-band signal, after its QAM modulation, into the additive white Gaussian noise channel transmission, and addition operations have been transferred signal superimposed white noise, simulated additive white Gaussian noise on the signal transmission channel impact in the receiving end of a corresponding signal demodulation, and compared with the original signal bit error rate calculation. Change the error of white noise power, signal to noise ratio and bit error rate mapping curve. And with the same group of other students to compare the performance curve modulation performance of the pros.
