Entropy-coding-source-program
- 熵编码(entropy encoding)是一类利用数据的统计信息进行压缩的无语义数据流之无损编码。本章先介绍熵的基本概念,然后介绍香农-范诺(Shannon-Fano)编码、哈夫曼(Huffman)编码、算术编码(arithmetic coding)、行程编码(RLE)和LZW编码等常用的熵编码方法。 哈夫曼编码建议了一种将位元进位成整数的算法,但这个算法在特定情况下无法达到最佳结果。为此有人加以改进,提供最佳整数位元数。这个算法使用二叉树来设立一个编码。这个二叉树的终端节点代表被编码的字母

turbo_code_5g
- 5G通信必须用到的编码:Turbo码是Claude.Berrou等人在1993年首次提出的一种级联码。基本原理是编码器通过交织器把两个分量编码器进行并行级联,两个分量编码器分别输出相应的校验位比特;译码器在两个分量译码器之间进行迭代译码,分量译码器之间传递去掉正反馈的外信息,这样整个译码过程类似涡轮(Turbo)工作。因此,这个编码方法又被形象地称为Turbo码。Turbo码具有卓越的纠错性能,性能接近香农限,而且编译码的复杂度不高。-5G communication must be used
