一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，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，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated,

这是我的论文要设计程序,通过设计QMF(CQF,OQF)滤波器,研究针对不同的滤波器阶数，采用批量算法，实现和比较波形编码的效率和精度-This is my thesis to the design process, through the design of QMF (CQF, OQF) filter to study the filter for different order, using bulk algorithms, and comparison of waveform coding
