提出一种新型的基于AWGs波导的采用扩展双曲同余码/素数码(EHLC/PC)结构的二维编/解码方案,并进行了计算机模拟,得到了二维EHLC/PC码的解码相关输出结果。结果表明:AWGs编解码器实现了二维EHLC/PC码字的编码和相关解码 在相同码长、码重的情况下,EHLC/PC码容量较大,可以实现更多用户的接入。此外,利用AWGs编解码器易于实现OCDMA编解码器的集成化。
A novel OCDMA en/decode scheme in wavelength/time domain is proposed. The scheme use the extend hyperbolic and linecode (EHLC)/prime code (PC) with arrayed waveguide grating (AWGs). The two-dimension EHLC/PC-code in the en/decoding scheme is investigated by computer simulation. It is indicated that the AWGs can be employed as en/decoder on basis of EHLC/PC-code. The more number of users can be accessed in the same code length and code weight in this system. Moreover, AWGs en/decoder is easy to be integrated.
