shannon code meaning in Chinese

香农码

Such code is also called gradually good code or shannon code . in 1993 , c . berro etc . firstly proposed a new channel code method - turbo code , which employed recursive systematic code 、 the random interleaver 、 map ( maximum a posteriori ) algorithm and iterative decoding algorithm obtained the capacity that had only 0 . 7db difference compared to the shannon limitation
1993年c . berro等首先提出了一种全新的信道编码方式? turbo码，采用递归系统码与随机交织器构造turbo码，并将map ( maximumaposteriori )算法和迭代算法应用于解码过程，获得了与香农理论极限仅差0 . 7db的性能。
