摘要

先前设计非系统涡轮码的尝试并没有取得比系统涡轮码更好的性能。本文提出了一种性能良好的新型非系统turbo码。这类新代码背后的思想是使用双非对称涡轮码，其中一个组成码是“递归非系统快速查找”代码，另一个组成码是“大分子累加器”。

Turbo codes with recursive nonsystematic quick-look-in constituent codes

Prior attempts at designing nonsystematic turbo codes have not achieved performances better than systematic turbo codes. This paper presents a new class of nonsystematic turbo codes that perform very well. The idea behind this new class of codes is to use a doubly-asymmetric turbo code where one of the constituent codes is a "recursive nonsystematic quick look-in" code, and the other constituent code(s) is a "big numerator accumulator".
