چکیده
Optical code division multiple access (OCDMA) shows limitations in terms of the inefficient bandwidth utilization and low spectral density with one-dimensional (1D) codes. To overcome these limitations, a novel design is presented using two dimensional (2D) spectral/spatial multiwavelength coding scheme. The proposed constructed 1D balanced incomplete block (BIBD) technique. Theoretical analytical results indicate that provided improvement number simultaneous users, construction, cross-correlation minimized noise. Moreover, requirements can be minimized, it provide flexibility addressing sequences. Finally, were compared existing spectral-spatial 2D codes such as diagonal eigenvalue unity (DEU) diluted perfect difference (DPD). It was observed 2D-BIBD fulfilled optical transmission needs minimum effective source power (Psr = −27.5 dBm) when to 2D-DEU (−26.5 2D-DPD (−25.5 Overall, our suggested performance BER for 72% 22% higher than codes, respectively.

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 introduces multiple access interference (MAI) which primarily deteriorates the performance of OCDMA systems. This p...
