Effect of error correction coding on OCDMA system

A novel forward error-correct (FEC) scheme based on Reed-Solomon code (RS code) is proposed for optical code division multiple access (OCDMA) systems. The error-correcting ability of the presented FEC scheme for one-dimension and two-dimension OCDMA systems are simulated and analyzed. Researched results show that the bit error rate (BER) of OCDMA system using FEC technology is better than that withoutwit using FEC technology at the condition of same code length and code weight. And the capacity is also largely enhanced due to the application of FEC technology. Moreover, for the address code of OCDMA system coming from the same code family, the BER is improved with the increase of the code weight.
