Abstract :
This paper presents security performance for incoherent unipolar and bipolar Optical CDMA Network Systems. The eavesdropper performance is investigated, by simulation, based on Modified Double Weight (MDW) Spectral Amplitude Optical CDMA. Our results show that using unipolar OCDMA code schemes based on MDW code system enhances the security with a low cost implementation in comparison to the bipolar ones.
