| Summary: | Optical Parallel Interference Cancellation (OPIC) is effective technique to reduce the Multiple Access Interference (MAI) in the Optical Code Division Multiple Access (OCDMA). However, the increasing demands for hardware in the OPIC system results into more complexity, higher processing time and cost. In this paper a new receiver is presented which is based mainly on the Optical Parallel Interference Cancellation (OPIC) for the Optical Code Division Multiple Access (OCDMA) local area networks. Optical Orthogonal Code (OOC) is adopted as a signature sequence for the performance analysis and a new expression for the error probability is derived. The results show that the proposed method is effective to reduce the hardware complexity, processing time and cost while maintaining the same bit error probability at the cost of increasing the threshold value. ©2007 IEEE.
