Tandem Spreading Network-Coded Division Multiple Access
IEEE Transactions on Industrial Informatics, 2017Massive 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.

A semiclassical analysis of optical code division multiple access
IEEE Transactions on Communications, 1991A 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 ...

A Code-Division Multiple-Access Local Area Network
IEEE Transactions on Communications, 1987In 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.

Optical Code Division Multiple Access
1998The 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.

Code division multiple access networks
1985This 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.

Code Division Multiple Access (CDMA)
2018This 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.
