Wave passive network security research based on improved SAC code of OCDMA

将改进光谱幅度编码用于OCDMA的波分复用无源光网络系统,通过数学推演分析了该编码的网络性能表现。实验表明,改进后的系统比特误码率低于10-10,多址干扰在一定程度上被抑制,传输网络的性能稳定且波动较小,编码方案随机性较强,入侵难度增加,系统的保密性得到了相应的增强。

Abstract：Wavelength division multiplexing passive optical network system based on improved spectral am- plitude coding for OCDMA, through mathematical deduction analyse the encoded network performance. The experiments demonstrate that the improved bit error rate of less than 10-10, the multiple access interference is suppressed to some extent, a stable performance of the transmission network and the less volatile, random stronger coding scheme, increasing the difficulty of intrusion, the system confidentiality is enhanced accordingly.
