Abstract

A pulse‐position modulation (PPM) optical CDMA system with interference estimation and cancellation is proposed. Multiuser interference is estimated with the aid of modified prime code sequence properties. A comparison between the bit‐error rate (BER) of both the proposed system and the system without cancellation reveals that the former system improves the BER performance significantly. © 2001 John Wiley & Sons, Inc.

## Abstract Interference reduction via a cancellation scheme for synchronous optical CDMA systems is discussed. Based on integrating over one bit duration of the received optical signal, the interfering signals can be estimated and cancelled by the desired correlator. Irrespective of high or low lo

In this paper, a cancellation technique using a reference signal which does not contain the components of the desired signal is proposed for optical synchronous M-ary FSK/CDMA. As spreading codes, the modified prime sequence codes which can increase the number of users are employed. Interference can

This letter analyzes the performance of M-ary orthogonal signaling in an FO-CDMA communication system employing optical orthogonal codes. The BER probability is e¨aluated by assuming Gaussian statistics for the recei¨er output. The numerical results illustrate that M-ary orthogonal signaling in an F
