When mapping is applied for the double weight code family to increase the number of users, for spectral amplitude coding optical code division multiple access (SAC OCDMA) systems, the conventional complementary detection technique cannot be used to retrieve the intended signal because of the unfixed cross-correlation value between different code sequences. This paper studies the software simulation...
This project concentrates on the effects detection technique to the system performance of spectral amplitude coding optical code division multiple access (SAC- OCDMA). The system employed the encoder and decoder modules based on the fiber Bragg gratings (FBGs) to generate the unique code sequences for the users. These modules are basically designed for the modified double weight (MDW) code which allows...
The subtraction detection techniques for a hybrid SCM spectral-amplitude-coding (SAC) OCDMA using double weight (DW) code family are investigated. The experimental simulation results show that the proposed new subtraction detection technique provides a better system performance.
