| 摘 要： | 对光CDMA编解码器在的误差及其对系统误码率的影响进行了分析，研究了表明：对于时间编码系统，编解码器的误差都将引起信噪比的损失而导致误率上升；光谱编码系统受误差的影响要比时间编码系统大；光谱编码系统的可容纳用户数比时间编码系统多，误码率也低得多。

| Abstract: | This paper analysed the manufacturing errors of encoder /decoder of OCDMA and the effects on system's BER. The research results indicated that for both the optical spectrum encoding system and the time encoding system, the errors of encoder/decoder will cause the degradation of SNR and increase of BER; the influence of these errors on the optical spectrum encoding system is more serious than that on the time encoding system, in addition, the optical encoding system can accommodate more users and have lower BER than that in the time encoding system. |
