An innovative encoding/decoding architecture based on two-code keying for SAC-OCDMA systems

An elegant encoding/decoding architecture based on two-code keying scheme for high-rate transmission in non-coherent spectral-amplitude-coding optical code-division multiple-access (SAC-OCDMA) systems, is suggested. To evaluate the performance improvement, a commercial OptiSystem software (Version 12.2.1) is used. The simulation results show that SAC-OCDMA system using the proposed architecture exhibited an enhanced performance.
