Spread-spectrum communications

IEEE Potentials, 1993
The characteristics of spread-spectrum systems that account for their growing use are examined. They offer low probability of intercept, signal hiding, and jammer rejection. Spread spectrum also provides a measure of immunity to multipath interference and multiple access capability, making it ideal for radar, telephone, local area networks, and many ...

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.

Quantum Spread Spectrum Communication

Conference on Lasers and Electro-Optics 2010, 2010
We demonstrate that spectral teleportation can coherently dilate the spectral probability amplitude of a single photon. In preserving the encoded quantum information, this variant of teleportation subsequently enables a form of quantum spread spectrum communication.

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.

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.

Performance Criteria for Spread Spectrum Communications

IEEE Transactions on Communications, 1977
The criteria for antijam (AJ) and anti-intercept (AI) systems are described, in terms of the appropriate action taken by the jammer or interceptor. Avoiding pseudonoise (PN) sequences which can be partially or totally predicted is a foremost criteria, especially for AJ, and use of nonlinear feedforward logic (NFFL) with long-period linear maximal ...

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.
