摘　　要：无中继长线传输会出现信宿端信号严重失真的现象,矫正器是长线传输系统中的重要一环。本文提出一种对长线传输系统中HDB_3编码的失真信号进行矫正的算法。该算法采用先进先出队列并结合HDB_3编码规律进行码元矫正。最后给出了仿真结果。结果表明,误判率得到有效控制。The signal＇s high frequency part attenuates seriously on the no repeater long-line transmission systems, so that the signal rectification is necessary. This paper researches a rectification algorithm to HDB3 coding distortion on the non-repeated long-line transmission systems. FIFO is adopted according to HDB3 coding and its distortion waves in the rectification. At last the simulative result is presented. The result indicates the error properbility is controlled effectively.
