摘要

提出了Turbo解码冗余数系统(RRNS)码，并对其性能进行了评价。RRNS (n,k)码是一种最大最小距离分组码，具有与RS (Reed-Solomon)码相同的距离属性。因此它们的纠错能力由t=(n-k)/2给出。为了接受软输入和提供软输出，我们对经典的Chase算法进行了改进。利用提出的软输入软输出(SISO)追逐算法，实现了RRNS码的turbo译码。

Iterative decoding of redundant residue number system codes

Turbo decoded redundant residue number system (RRNS) codes are proposed and their performance is evaluated. An RRNS (n,k) code is a maximum-minimum distance block code, exhibiting identical distance properties to Reed-Solomon (RS) codes. Hence their error correction capability is given by t=(n-k)/2. We adapt the classic Chase algorithm in order to accept soft inputs and to provide soft outputs. Using the proposed soft input soft output (SISO) Chase algorithm, the turbo decoding of RRNS codes is contrived.
