Construction and Performance Studies of a Pseudo - Orthogonal Code for Fiber Optic Cdma Lan

Design and Performance Analysis of a New Family of Wavelength/Time Codes for Fiber-Optic CDMA Networks

Asynchronous multiplexing schemes are efficient than synchronous schemes, in a bursty traffic environment of multiple access local area network (LAN), as fixed bandwidth is not allocated among the users and there is no access delay. FiberOptic Code-Division Multiple Access (FO-CDMA) is one such asynchronous multiplexing scheme suitable for high speed LAN networks. While FO-CDMA offers potential...

Construction and performance analysis of a new family of optical orthogonal codes for CDMA fiber-optic networks

Frame time-hopping fiber-optic code-division multiple access using generalized optical orthogonal codes

In this paper, a new spreading technique for intensity modulation direct detection fiber-optic code-division multiple-access (FO-CDMA) communication systems is proposed. This new spreading technique is based on generalized optical orthogonal codes (OOC) with large cardinality and minimal degradation in performance when compared with a more optimum system, namely, an optical CDMA system using OO...

Performance analysis of slotted fiber-optic code-division multiple-access (CDMA) packet networks

This paper examines code-division multiple-access (CDMA) techniques used in slotted fiber-optic packet networks. Since the inherent properties and signal processing of the conventional communication channels are different from those of the fiber-optic channels, new code sequences must be constructed for fiber-optic applications. The goal of our research is to analyze the performance of fiber-op...

Reducing the Limitation on Application of Synchronous Decorrelating Detector Cdma Systems

In CDMA (Code - Division Multiple - Access) systems multi - user accessing of a channel is possible. Under the assumptions of Optimum multi - user and decorrelating detector in CDMA systems. By using signals with zero and / or identical cross correlations, a simple and expandable decorrelating detector with optimum efficiency which can be easily implemented are proposed. Constructing these sign...
