“…In SAC-OCDMA systems, it has been shown that MAI can be suppressed either by using fixed in-phase cross-correlation codes with subtraction detection techniques or via utilizing zero cross-correlation (ZCC) codes with direct detection technique [6], [7]. SAC-OCDMA systems may be used in inter-vehicle communication (IVC) [8], free-space optics (FSO) [9], and future optical communications networks [10]. Nevertheless, SAC-OCDMA systems are plagued with phase-induced intensity noise (PIIN) that arises from the non-coherency of the broadband sources of various transmitters [11].…”

An elegant encoding/decoding architecture based on two-code keying scheme for high-rate transmission in non-coherent spectral-amplitude-coding optical code-division multipleaccess (SAC-OCDMA) systems, is suggested. To evaluate the performance improvement, a commercial OptiSystem software (Version 12.2.1) is used. The simulation results show that SAC-OCDMA system using the proposed architecture exhibited an enhanced performance.

“…However, these sources are considered as Thermal sources that generate intensity noise (IN) at photo detection [4]- [7]. Intensity noise or phase induced intensity noise (PIIN) is the fluctuation in the photocurrent resulting from the square law of photo detection.…”

“…PIIN is a signal dependent source of noise, which increases with the increase in the signal strength, eventually leading to bit error rate (BER) floor. For incoherent sources, IN is directly proportional to the electrical bandwidth (B e ), and inversely proportional to the optical bandwidth (B o ) [7].…”

Intensity noise (IN) or phase induced intensity noise (PIIN) is the key limiting factor of the performance in spectral amplitude coding optical code division multiple access (SAC OCDMA) systems. The PIIN can be mitigated in SAC OCDMA by splitting the signals and detecting each signal by a different photodiode if the independence between the split signals can be achieved. In this paper, we derive the upper and lower bounds for the bit error rate (BER) for a system that implements multiple photodiode structured balanced detectors. Additionally, a simulation using Optisystem is conducted to compare the performance of the conventional balanced detector and an ideal multi photodiode balanced detector.Keywords-optical code division multiple access, spectral amplitude coding, intensity noise, phase induced intensity noise, balanced detection, and multiple photodiode balanced detection.

“…Recently Optical code-division multiple-access (CDMA) systems are becoming more and more attractive in the field of all-optical communications as multiple users can access the network asynchronously and simultaneously with high level of security [3,4]. Optical Spectrum Code-Division Multiple-Access (OSCDMA) is a multiplexing technique adapted from successful implementation in wireless networks.…”

Spectral Amplitude Coding (SAC)-OCDMA Network with 8DPSK

Optical code division multiple access (OCDMA) technique is required to meet the increased demand for high speed, large capacity communications in optical networks. In this paper, the transmission performance of a spectral amplitude coding (SAC)-OCDMA network is investigated when a conventional single-mode fiber (SMF) is used as the transmission link using 8DPSK modulation. The DW has a fixed weight of two. Simulation results reveal that the transmission distance is limited mainly by the fiber dispersion when high coding chip rate is used. For a two-user SAC-OCDMA network operating with 2 Gbit/s data rate and two wavelengths for each user, the maximum allowable transmission distance is about 15 km.
