摘　　要：以RSC(Reed-solomon codes,RSC)作为时间扩频序列,单重合序列(OCS)作为波长跳频序列,构造了一种新的时域/频域的二维光正交码RSC/OCS。在相同码重条件下,对RSC/OCS、2D-RSC的码字容量和误码率进行了比较;在相同码重和波长数条件下,对RSC/OCS、SQPC/OCS和EPC/OCS的误码率进行了仿真比较;最后,对RSC/OCS在OCDMA系统中的误码特性也进行了仿真分析。A new time/frequency two-dimensional optical orthogonal code named RSC/OCS was constructed with RSC （Reed-solomon codes） as time spreading sequence and one-coincidence sequence （OCS） as wave- length hopping sequence.The word capacity and the performance of bit error ratio （BER） of RSC/OCS were compared with that of 2D-RSC by simulation when given the same code weight; the BER of RSC/OCS were compared with that of SQPC/OCS and EPC/OCS when given the same code weight and same number of wave lengths;, finally the BER of RSC/OCS in the OCDMA system was analyzed by simulation.

关 键 词：OCDMA系统 RSC 单重合序列 误码率
