Abstract
本文設計了兩個解(23,12)Go1ay碼之演算法，此二演算法利用通道計量
資訊的協助使其具有解四個錯誤位元之能力。對於AWGN通道而言，所提之演
算法解碼效應要比以傳統HDD方式解碼好0.8分則。此外，第一個演算法所需
之解碼時間很短，第二個演算法較簡單且動作規律而十分適合做硬體實現。本文
亦提出了一個以第二個演算法為基礎所設計的硬體線路，此線路具有管線的特
性，所以解一個接收到的區塊碼位元僅需一個系統時序脈波。
Two new algorithms for decoding the (23,12) binary Glolay code are developed with channel measurement information. For a white Gaussian noise channel each of the two algorithmsachieves about 0.8 dB of decoding performance over a conventional hard-decision decodingwhen the probability of output bit error rate is 10?笐?. Furthermore, one of the algorithms requires a very small amount of computation for decoding a received block, and the other is verysuitable for hardware implementation owing to its simple and regular operation. The hardwaredecoder based on the latter algorithm is designed with pipeline such that it decodes one bit ofa received block in a single system clock cycle.
