摘　　要：讨论了基于FBG的谱幅编解码spectral-amplitude-coding(SAC)系统的原理;提出了)1,1,1(),,(2+++=qqqwNl光正交码的SAC编解码器实现方案;给出了该系统在码分功率不均匀时,以多址干扰为主的系统信噪比和误码率。分析了谱幅编解码OCDMA系统的应用前景。The scheme of FBGs-based OCDMA spectral-amplitude-coding(SAC) for OCDMA system with optical orthogonal code is discussed; The designing and the achievement process of SAC encoder/decoder with)1,1,1(),,(2+++=qqqwNlare firstly submitted; The performance of this system, the SIR and BER resulted from multi-access interference (MAI), are also analyzed in detail under the condition that the powers of code chips are not uniform; the applied foreground of this system is predicted.
