SAC-OCDMA With Zero Vector Combinatorial Code (ZVCC)
In this paper the performance of the incoherent SAC-OCDMA system using Zero Vector Combinatorial Code (ZVCC) has been observed by varying the code length and data rate. ZVCC is better than the other proposed code as it has small code length, accommodates more number of users and the design algorithm is simple. The results have been observed and analyzed in terms of BER. The simulated results show that the system at code weight 4 accommodates around 99 users at effective power -10dBm and as data rate is increased the BER degrades. The comparative study of the system using ZVCC with Zero Cross-correlation Code has been carried out. The results indicate that ZVCC truly performs better than ZCC code.
