Jamming resistance capabilities of the Spectrally Phase Encoded OCDMA systems

Abstract

Although, enhanced security is often mentioned as a noticeable benefit of spectrally phase encoded optical CDMA (SPE-OCDMA) systems, the quantity and degree of security enhancement is not considered deeply in the literature. One of the facts in determining the degree of security is to assess the resistance capability of the system against various jammers attacks. In this paper, we introduce and model three types of jammers, namely (Pulse Jammer, Partialband Jammer, and Follower Jammer). We mathematically analyze the effects of the above jammers on the performance of the SPE-OCDMA systems that use On-Off Keying (OOK) modulation scheme. It is demonstrated that under certain conditions, the performance of the system can be dramatically degraded due to the jamming signals. Moreover, it is seen that the strongest jammer is the follower jammer.
