一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, the program uses 16QAM modulation, the source of a string of two binary modulation, with the Raised Cosine modulated baseband functions, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot using the minimum Euclidean distance decoding decision, bit error rate calculation.)
