Abstract(in English) | New interference cancellation technique is proposed for optical synchronous code division multiple access (CDMA) systems using pulse position modulation (PPM) signaling (PPM/CDMA) with modified prime sequence codes. In the proposed system, we use one of the modified prime sequence code in one group as a reference signal for other users in the same group. Thus the number of users is decreased only P in comparison with the system without canceller. Here the number of users of the system without canceller equals to P^2. The Poisson effects of the photodetection process is considered in our analysis. The upper bound on the bit error probability of optical synchronous PPM/CDMA systems with interference canceller is derived. We show that the proposed cancellation technique is effective to improve the bit error probability performance and the number of users increases for the same bit error probability as prime number increases. |
