2-Dimensional optical CDMA system performance with parallel interference cancellation

In this paper, we investigate the feasibility of a 2-Dimensional Optical Code Division Multiple Access (2D-OCDMA) system, with electronic coding and decoding functions. We develop a modified construction method of Multi-Wavelength Optical Orthogonal Codes (MWOOC) that permits high flexibility in the code parameters choice. The 2D code performance is calculated for a Conventional Correlation Receiver (CCR) and a more complex one, named Parallel Interference Cancellation (PIC) receiver. For example, for a Bit Error Rate (BER) ⩽10−9, and 30 simultaneous users, we show that contrary to the CCR, the use of a PIC receiver leads to workable 2D electric coding solutions.
