摘要 介绍了光纤色散对快跳频光码分多址 (FFH- OCDMA)系统结构 ,分析了系统性能并进行计算机仿真。结果表明 ,在 FFH- OCDMA系统中 ,光纤色散导致解码自相关光脉冲峰值功率和光脉冲取样能量的降低 ,进而导致系统误码率 (BER )的增加。最后 ,提出用改变判决门限的方法来降低色散对 The structure of a fast frequency hop(FFH) OCDMA system is introduced and the performance is analyzed by computer simulation.The results of simulation show that dispersion seriously reduces the peak power and sample energy on the FFH OCDMA system.Hence,bit error rate(BER) of system is increased by dispersion.At last,in order to decrease effects of dispersion on BER,one mean of threshold adjust is given.
