Incoherent SAC OCDMA System at 7×622Mbps

Performance and Confidentiality Comparison of Different Hybrid SAC/OCDMA-WDM Overlay Schemes

Code pulses of a spectral amplitude coding/optical code division multiple-access (SAC/OCDMA) system are overlaid onto a multichannel wavelength division multiplexing (WDM) system. Modified quadratic congruence (MQC) codes are developed as the signature codes for the SAC/OCDMA system. The developed code is to avoid the overlapping between signals of both systems with no use of notch filters. In ...

SOA/SPD-based incoherent SAC-OCDMA system at 9×5Gbps

SAC-OCDMA with Zero Vector Combinatorial Code (ZVCC)

In this paper the performance of the incoherent SAC-OCDMA system using Zero Vector Combinatorial Code (ZVCC) has been observed by varying the code length and data rate. ZVCC is better than the other proposed code as it has small code length, accommodates more number of users and the design algorithm is simple. The results have been observed and analyzed in terms of BER. The simulated results sh...

Novel Combinatorial Constructions of Optical Orthogonal Codes for Incoherent Optical CDMA Systems

Three novel classes of optical orthogonal codes (OOCs) based on combinatorial designs are proposed. They are applicable to both synchronous and asynchronous incoherent optical code-division multiple access (OCDMA) and compatible with spectral-amplitude-coding (SAC), fast frequency hopping, and time-spreading schemes. Simplicity of construction, larger codeword families, and larger flexibility i...

Enhanced Performance of SAC-OCDMA System based on SPD Detection Utilizing EDFA for Access Networks

In this paper, we present the impact of an EDFA (Erbium Doped Fibre Amplifier) for high data rate in Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) networks. A Single photodiode (SPD) detection structure for SACOCDMA system is presented. The SPD detection can be flexibly constructed for any weight and number of users by using a single photodiode. Several advantages ...
