چکیده
ohammad M. N. Hamarsheh rab American University, Jenin epartment of Telecommunication Engineering TCE aculty of Information Technology .O. Box 1: 240 Jenin Abstract. A successive interference cancellation scheme is applied to optical code-division multiple-access OCDMA systems with spectral amplitude coding SAC . A detailed analysis of this system, with Hadamard codes used as signature sequences, is presented. The system can easily remove the effect of the strongest signal at each stage of the cancellation process. In addition, simulation of the prose system is performed in order to validate the theoretical results. The system shows a small bit error rate at a large number of active users compared to the SAC OCDMA system. Our results reveal that the proposed system is efficient in eliminating the effect of the multiple-user interference and in the enhancement of the overall performance. © 2009 Society of Photo-Optical Instrumentation Engineers.
