A Review on Successive Interference Cancellation Scheme Based on Optical CDMA Network

Abstract

Due to various desirable features of optical code division multiple access (OCDMA), it is believed this technique once developed and commercially available will be an integral part of optical access networks. Optical CDMA system suffers from a problem called multiple access interference (MAI) which limits the number of active users, it occurs when number of active users share the same carriers. The aim of this paper is to review successive interference cancellation (SIC) scheme based on optical CDMA system. The paper also reviews the system performance in presence of shot noise, thermal noise, and phase-induced intensity noise (PIIN). A comprehensive review on the mathematical model of SIC scheme using direct detection (DS) and spectral amplitude coding (SAC) were presented in this article.

Multiplicative PIC detection for OCDMA systems with non‐negativity constraints

“…SIC and PIC detectors exhibit low computational complexity compared to the decorrelator and MMSE detectors. Several SIC and PIC detectors have been proposed in the literature [9][10][11][12][13][14]. For example in [9], an analytical comparison of optical code-division multiple-access systems with and without a SIC scheme using modified prime-sequence codes is conducted.…”

“…For example in [9], an analytical comparison of optical code-division multiple-access systems with and without a SIC scheme using modified prime-sequence codes is conducted. In [10], a SIC detector taking into consideration the shot noise, thermal noise, and phase-induced intensity noise is proposed. The same authors proposed another SIC detector using pulse position modulation (PPM) and spectral amplitude coding (SAC) [11].…”

Performance Enhancement of Optical PPM-CDMA Using Successive Interference Cancellation Scheme

“…Therefore, the suppuration or cancellation of the MAI has been the focus on the study of optical CDMA system. Several methods have been introduced and proposed to suppress or cancel the MAI [10]- [13].…”
