摘要

研究了Reed-Solomon码的代数软判决译码中的二元插值问题。推导了分层插值情况下的重编码变换。提出了一种基于分层、Lee-O'Sullivan和Kötter算法的混合插值算法。与迭代插值算法相比,该算法的复杂度大大降低。

Hybrid interpolation algorithm for algebraic soft decision decoding of Reed-Solomon codes
The problem of bivariate interpolation in algebraic soft decision decoding of Reed-Solomon codes is considered. Re-encoding transformation for the case of layered interpolation algorithm is derived. A novel hybrid interpolation algorithm based on layered, Lee-O'Sullivan and Kötter algorithms is proposed. The proposed algorithm demonstrates considerable complexity reduction compared to the case of iterative interpolation algorithm.
