On the construction of 2/sup n/ codes for optical code-division multiple-access

IEEE Transactions on Communications, 1995
An optical orthogonal code (OOC), intended for optical code-division multiple-access (CDMA), is a collection of (0,1) sequences with good correlation properties (i.e., high autocorrelation peaks with low sidelobes, and low crosscorrelation values). A "serial" coding architecture for optical CDMA has been introduced and found particularly suitable for ...

A Code-Division Multiple-Access Local Area Network

IEEE Transactions on Communications, 1987
In this paper, we propose a code-division multiple-access (CDMA) approach as a method of local area networking, and analyze its physical performance. The proposed system has the advantage of a multiehannel multiaccess local area network, and provides the capability of easy access to different kinds of traffics, such as voice and data.

Broadband code division multiple access

1996 IEEE Aerospace Applications Conference. Proceedings, 2002
The use of code division multiple access (CDMA) techniques for wireless communications systems, both terrestrial based and satellite based, has become of interest because of certain distinctive characteristics of spread spectrum waveforms relative to those of more conventional signals.

A semiclassical analysis of optical code division multiple access

IEEE Transactions on Communications, 1991
A model noncoherent, optical, asynchronous, CDMA system is described. The error rate for a single-user matched-filter receiver that is valid for arbitrary photomultipliers and signature sequence sets, adheres to the semiclassical model of light, and does not depend on approximations for large user groups, strong received optical fields, or chip ...

Optical Code Division Multiple Access

1998
The code division multiple access (CDMA) is under consideration for broadband video delivery over fiber-optic local area networks (LANs). There are several approaches for implementing classical CDMA principles in the optical domain, classified as incoherent, coherent and approaches based on encoding in frequency spectrum.

Tandem Spreading Network-Coded Division Multiple Access

IEEE Transactions on Industrial Informatics, 2017
Massive machine-type communication (MMTC) is the key technology to meet the flourishing Internet of things industry. One prominent characteristic of MMTC is massive connections which brings a critical challenge of multiple access interference (MAI) on channel estimation, user identification, and data detection.

Code Division Multiple Access (CDMA)

2018
This chapter presents a brief overview of spread spectrum technique and shows how it relates to CDMA technology. Orthogonal codes and their properties are presented and show how orthogonal codes are generated and used to design CDMA radio. It is shown that CDMA capacity directly relates to code length.

Code division multiple access networks

1985
This chapter discusses code division multiple access networks. The spread spectrum code division multiple access techniques requires the construction of spreading codes giving rise to a minimum of interlink interference. However, situations arise where the effects of interlink interference are amplified owing to operational considerations.
