摘要 编织码 ( Woven码 )是一类包容性极强的新型高效纠错码 ,它是在级联码的基础上形成的 ,其编码结构具有把各类成员码按编织状组合编码的特点且其性能优于传统的 Turbo码。本文在简要阐述编织码的三种基本编码原理基础上对外经结构的不同编码方案构成的编织码做了简单的分类 ,这对优化设计和分析编织码性能具有积极推动作用。 Woven codes based on concatenated codes are a new combination error-correcting codes with high compatibility, and their encoding constructions have a character combining the constituent codes according to the fabric twill, and their performance is more advantageous than that of traditional Turbo codes. The classification of Woven codes with outer warp is analyzed based on the three basic encoding principles of Woven codes, which is significant for to optimize design and analyze performance of Woven codes.
