Security becomes the critical issue in incoherent spectral amplitude coding optical code division multiple access (SAC-OCDMA) systems. In preventing the unintended users from decoding and extracting the data due to the cross-correlation among code sequences, an ideal detection technique is needed to enhance the security of the SAC-OCDMA systems. In this paper, we study the efficiency of the modified-AND...
Multiple-access interference (MAI) and phase-induced intensity noise (PIIN) are the principal limitations for the performance of spectral-amplitude-coding optical codedivision multiple-access (SAC-OCDMA) systems. Focusing on increasing the performance and reducing the bit-error rate (BER), the ideal transceiver design should be accentuated. In this paper, we studied the effect of the different combination...
Non-return-to-zero (NRZ) and return-to-zero (RZ) are two basic data formats in optical communication systems. In this paper, we compare the performance of NRZ against RZ with both AND as well as modified-AND subtraction detection techniques in spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. Modified double-weight (MDW) codes are used as the signature codes for...
Progress in fiber optic technology have made long-haul communications systems reach distance that were once unheard of. This distance is made possible by using modulation techniques that do not require a complex link design which best applied in spectral-amplitude coding optical code-division multiple access (SAC-OCDMA) system. In this paper, we investigate the use of different detection schemes namely...
