依据目前已有的数据对未来的发展趋势做出预测分析，进行灰度分析的。(Based on the current analysis of existing data to predict future trends, grayscale analysis.)

有关PCM编码的，并有误码率分析，无密码(The PCM coding, no password)

卫星通信系统格状编码调制，附有详细文档和源码(Satellite communication systems trellis coded modulation, with detailed documentation and source code)

设有离散无记忆信源X,P(X)．二进制费诺编码为：1.将信源符号按概率从大到小的顺序排列2.将信源分成两组――按两组概率之差为最小分．3.上面一组编码为0，下面一组编码为1，一直分到一组只有一个信源为止．4.将一个信源分组得到的0和1全部连接起来，组成该信源的码字，信源即得到自己的费诺编码．(There be no X remembering the message source in case that having being scattered, binary Feinuo of P (X) code is: 1. Will believe that the source sign orders 2 according to probability is minor from arriving at greatly sequence. Will believe that the source divides into two part being allotted 3 according to two set of bad of probability for the minimum. A group of code is 0 above , a group of code is 1 underneath, till dividing till a group only when one believes a source 4. Get up with a 0 and 1 all connection believing that the source is divided into groups and , be composed of the codon owing message a source , believe that the source is to get self Feinuo code Powered )
