摘　　要：分析了STOOC码字的设计方案及码重、互相关性、系统容量等性能,仿真出几种适合SAC-OCDMA系统码字的多址干扰误码率与并发用户数的关系,结果表明:STOOC码字容量达到了SAC的上限;STOOC码字的编解码比其它几种码字更容易,且非常适合光谱幅度编码(SAC)光码分多址(OCDMA)系统;得出了在STOOC码字的系统多址干扰误码率比其他码字小,在一定误码率要求下,STOOC码字比其他码字可以承载更多的并发用户。The designing process of STOOC and the performance of code-weight, correlation and capacity of the system are analyzed. The relationship schema between the bite- error rats and the number of simultaneous users is emulated. The analysis results indicate that the capacity of STOOC has reached the upper limit of SAC; STOOC can code and decode much easier than others and it can be adapted to the system of SAC-OCDMA. It is conclued that the BER of optical code-division multiple access in the STOOC system is lower than other codes for SAC and more simultaneous users can be held when BER is controlled under a certain standard.
