In this paper, we propose a developed detection technique named the modified-AND subtraction detection for incoherent SAC-OCDMA systems. This detection technique is based upon decreasing the received signal strength during the decoding process by dividing the spectrum of the utilized code sequence. The proposed technique is capable of mitigating the intensity noise effect, as well as suppressing the multiple-access interference impact. Based on modified quadratic congruence (MQC) code, the analytical results reveal that the modified-AND detection offer best bit-error rate (BER) performance and enables MQC code to support higher transmission rate up to 1.25Gb/s compared to conventional AND detection. Furthermore, we ascertained that the proposed technique enhances the system performance using a simulation experiment. 2013-03-08T01:32:54Z 2013-03-08T01:32:54Z 2012-06 Article Journal of Modern Optics, vol. 59 (10), 2012, pages 878-886 0950-0340 http://www.tandfonline.com/doi/abs/10.1080/09500340.2012.676094 http://hdl.handle.net/123456789/23992 en Taylor and Francis Group, LLC.
