Abstract

Optical code division multiple access (OCDMA) provides  another dimension to multiple access systems,  in which each user is assigned a unique code. This allows  each subscriber  to simultaneously access the medium without any contention. However, simultaneous access of multiple users introduce multiple access interference  (MAI)  which primarily deteriorates  the performance of OCDMA systems.  This paper proposes a new code called diagonal double weight (DDW) code to elevate the performance and cardinality of spectral amplitude coding  (SAC) OCDMA  systems. Performance of our proposed code is evaluated using comprehensive analytical  analysis  followed by simulation analysis. Examination  of bit error rate shows that DDW code along with  single photodiode detection  technique  provides efficient performance, with added benefits of simplified design, large cardinality and ease of implementation.
