System Performance Comparison of Turbo and Trellis Coded Optical CDMA Systems

In this paper, the authors have compared the performance of a Turbo and Trellis coded Optical Code Division Multiple Access (OCDMA) system. The comparison of the two codes has been accomplished by employing Optical Orthogonal Codes (OOCs). The Bit Error Rate (BER) performances have been compared by varying the code weights of address codes employed by the system. They have considered the effects of Optical Multiple Access Interference (OMAI), thermal noise and Avalanche PhotoDiode (APD) detector noise. Analysis has been carried out for the system with and without Double optical Hard Limiter (DHL).
