This paper introduces a hybrid optical Code division multiplexing (OCDMA) over wavelength division multiplexing (WDM) system with differential phase shift keying (DPSK) modulation using direct and complementary subtraction detection techniques. Two different technologies namely, OCDMA and WDM are combined together as a hybrid system to increase the transmission capacity, security and reliability of...
This paper propose a new code to optimize the performance of spectral amplitude coding-optical code division multiple access (SAC-OCDMA) system. The unique two-matrix structure of the proposed enhanced multi diagonal (EMD) code and effective correlation properties, between intended and interfering subscribers, significantly elevates the performance of SAC-OCDMA system by negating multiple access interference...
The bit-error rate (BER) performance of the spectral amplitude coding-optical code division multiple access (SACOCDMA) system has been investigated by using NAND subtraction detection technique with enhanced double weight (EDW) code. The EDW code is the enhanced version of double weight (DW) code family where the code weight is any odd number and greater than one with ideal cross-correlation. In order...
