中文摘要：
基于基因算法(GA ) ，译码的新基因可能性(GPD ) 为修正(FEC ) 在光传播系统编码的前面的错误的计划被建议。GPD 计划能进一步由使用隧道干扰概率和统计信息恢复最大的可能性的传动代码词抵消难决定的 quantification 误差。理论表演分析和建议 GPD 计划有的优点的模拟结果表演降低译码复杂性，更快的译码速度和更好的译码修正错误性能。因此，建议 GPD 算法是一个更好实际的译码算法。
英文摘要：
Based on the genetic algorithm（GA）,a new genetic probability decoding（GPD） scheme for forward error correction（FEC） codes in optical transmission systems is proposed.The GPD scheme can further offset the quantification error of the hard decision by making use of the channel interference probability and statistics information to restore the maximal likelihood transmission code word.The theoretical performance analysis and the simulation result show that the proposed GPD scheme has the advantages of lower decoding complexity,faster decoding speed and better decoding correction-error performance.Therefore,the proposed GPD algorithm is a better practical decoding algorithm.
