The Origins of Spread-Spectrum Communications

IEEE Transactions on Communications, 1982
This monograph reviews events, circa 1920-1960, leading to the development of spread-spectrum communication systems. The WHYN, Hush-Up, BLADES, F9C-A/Rake, CODORAC, and ARC-50 systems are featured, along with a description of the prior art in secure communications, and introductions to other early spreadspectrum communication efforts.

Spread spectrum communications: myths and realities

IEEE Communications Magazine, 1979
Spread spectrum communication techniques date back to the early fifties. Since the earliest applications, system improvements have been more evolutionary than revolutionary. Like most improvements in electronic systems, these are due primarily to the availability of ever higher speed integrated circuit components, which translate in this case ...

A spread spectrum communications channel sounder

IEEE Transactions on Communications, 1997
The design of a microwave channel probing analyzer is presented and discussed. Special attention is paid to the characteristics of the transmission path to be measured; the choice of spread spectrum probing signal; the signal processing methods used; modulation, demodulation, and synchronization at the transmitter and receiver sites; the path model to ...

Combination Sequences for Spread Spectrum Communications

IEEE Transactions on Communications, 1977
Certain communication systems which employ spread spectrum techniques as a means of supporting multiple users need very long codes to guard against the threat of intentional jamming, but cannot tolerate the lengthy acquisition time which long codes usually require.

Spread-Spectrum Communication

2023
Abstract One of the first applications of the wartime and postwar informational studies of noise was the spread-spectrum technology that scrambled transmitted signals in a communication system for encryptive or antijamming purposes. These scrambled signals effectively “rode on” a noisy carrier.

Spreading codes for wireless spread spectrum communications

Proceedings of ICC/SUPERCOMM '96 - International Conference on Communications, 2002
Spread spectrum techniques are often utilized when designing wireless communication systems. The success of a spread spectrum system depends greatly upon the spreading codes employed by the transmitters. In this paper, a novel approach to the generation of spreading codes is examined.

Spread-spectrum communication techniques

Electronics & Communication Engineering Journal, 1994
Spread-spectrum modulation can be used in a radio system to reduce the likelihood of intercept, as well as providing some protection against jamming and interference. These antijam, anti-interference and low-probability-of-intercept properties are highly desirable in secured communication systems.

Underwater spread-spectrum communications

Oceans '97. MTS/IEEE Conference Proceedings, 2002
For low data rate communications, spread spectrum techniques can be used in the underwater medium. They fight intersymbol interference caused by multipath propagation. They have to be used if the signal-to-noise ratio (SNR) is inferior to 0 dB. They are particularly interesting for anti-jamming or discretion purposes.

Spread spectrum for mobile communications

IEEE Transactions on Vehicular Technology, 1991
The characteristics of spread spectrum that make it advantageous for mobile communications are described. The parameters that determine both the performance and the total capacity are introduced, and an analysis which yields (approximately) the number of users that can simultaneously communicate, while maintaining a specified level of performance, is ...

SPREAD SPECTRUM COMMUNICATION VIA CHAOS

International Journal of Bifurcation and Chaos, 1999
A new scheme is proposed for spread spectrum communication which transmits both analog and binary data via chaotic carriers. The proposed systems have some standard properties of spread spectrum communication. Some computer simulations and performance analysis are given to examine the validity of this scheme.
