摘要

在这种网络中，每个编码器/解码器对由两个订户共享。然而，高强度引起的相生强度噪声(PIIN)会降低系统的性能。为了抑制PIIN，使用相同编码器的用户在相互正交的极化上发射信号，并采用具有多个平衡检测器的接收机结构

Multilevel Optical CDMA Network Coding with Embedded Orthogonal Polarizations to Reduce Phase Noises

A spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) system with four-level intensities and polarization-division-multiplexing (PDM) is presented. Each encoder/decoder pair is shared by two subscribers in such a network. However, phase-induced intensity noise (PIIN) induced by high intensities deteriorates the system performance. To suppress PIIN, users sharing the same encoder transmit signals on mutually orthogonal polarizations, and the receiver structure with multiple balanced detectors is employed
