Abstract

In this paper, comparative analysis of code performance of distinct optical 2-D codes belonging to the Prime code family have been examined. Various optical 2-D Prime codes such as Low-weight Prime sequence code (LW-PSC), Modified prime-hop code (MPHC), Extended prime-hop code (E-CHPC), Transposed-modified prime code (T-MPC), Transposed-sparse padded modified prime code (T-SPMPC) are considered. Hard-limiting Error Probability (HEP) equations of these codes are used to scrutinize the performance of these codes. Performance of one of the 2-D Prime codes, more specifically MPHC performs best in OCDMA systems where only Multi-user interference effect is considered. This optical 2-D MPHC code possesses very low BER value as compared to universally accepted standard with the increasing user count. MPHC provides robustness to multiple user interference affected OCDMA therefore very much apt for applications where simultaneous access of immense number of active user is required.
