Abstract This paper proposes a new coding scheme for spectral amplitude coding (SAC) family, known as Sigma Shift Matrix (SSM). Two techniques are proposed for the design of SSM coding scheme. The first technique combines the identity and upper shift matrices to form an SSM coding matrix named as SSMI. The second approach adapts the assembly of a single – entry, lower and upper shift matrices to compose another SSM matrix called SSMs. Combination of these matrices generates variable SSM code families, which can provide more flexibility in code weight selection and the number of users respectively. Furthermore, a modified SSM (MSSM) coding scheme is proposed through bitwise ANDing of SSMI and SSMS to further elevate performance of the proposed setup. The optimized structure of SSM coding scheme eliminates the influence of multiple access interference (MAI) and alleviate the effect of phase induced intensity noise (PIIN). Numerical results show that MSSM, SSMI and S S M S SSMS outperform the existing coding schemes in descending order and proves to be an efficient candidate for the implementation of high capacity next generation of optical communication networks.

一种可配置的发射器-接收器结构，用于支持频谱幅度编码-光码分多址的 QoS

摘要 本文提出了一种新的频谱幅度编码（SAC）系列编码方案，称为Sigma Shift Matrix（SSM）。提出了两种技术来设计 SSM 编码方案。第一种技术将单位矩阵和上移矩阵组合起来，形成一个名为 SSMI 的 SSM 编码矩阵。第二种方法采用单个条目、下移和上移矩阵的组合来组成另一个称为 SSM 的 SSM 矩阵。这些矩阵的组合产生了可变的 SSM 代码族，可以分别在代码权重选择和用户数量上提供更大的灵活性。此外，通过对 SSMI 和 SSMS 进行按位与运算，提出了一种改进的 SSM (MSSM) 编码方案，以进一步提高所提出设置的性能。SSM编码方案的优化结构消除了多址干扰（MAI）的影响，减轻了相位感应强度噪声（PIIN）的影响。数值结果表明，MSSM、SSMI 和 SSMS SSMS 在降序方面优于现有的编码方案，并被证明是实现高容量下一代光通信网络的有效候选方案。
