说明：  （2,1，2）归零卷积码的维特比译码算法matlab实现((2,1,2) convolutional codes Viterbi decoding)

我们确定数字滤波器的幅度函数并画出幅度函数图。(We define digital filter amplitude function and draw the amplitude function diagram.)

最速下降法优化，无约束，可以自己改进。很容易懂有简单的说明。(Steepest descent method optimization, non-binding, can improve. There is a simple easy to understand explanation.)

格式 [sqnr,a_quan,code]=u_pcm(a,n) 输入样值序列a 、量化电平数目n, 程序计算量化间隔、进行均匀量化、进行编码、计算量化信噪比， 返回量化信噪比squn、编码前的量化序列a_quan、编码后的码序列code。 (Format [sqnr, a_quan, code] = u_pcm (a, n) input sample value sequence a, the number of quantization levels n, the calculation procedures to quantify interval, the uniform quantization, coding, computing quantization noise ratio, return quantization noise ratio squn, to quantify the pre-coding sequence a_quan, coding sequences after the code.)

hai this is useful for wavelet programming

说明：  各种数字水印的MATLAB源码+论文，新手可以研究研究(MATLAB source code of various digital watermarking+ Papers)
