Notes on Spread-Spectrum History

IEEE Transactions on Communications, 1983
This paper presents additional historical information relating to the spread-spectrum history described in [1]. Included here are ties with speech scrambling technology, wide-band matched filter design, stimulus of the WHYN system design by British research, ITT's efforts to protect vital information during World War II, and other miscellaneous notes ...

A spread spectrum network analyser

ISSPA '99. Proceedings of the Fifth International Symposium on Signal Processing and its Applications (IEEE Cat. No.99EX359), 2003
The paper describes the realisation of a spread spectrum network analyser using appropriate software to control a PC interface card, like a soundcard. The software generates a digitised time waveform consisting of a spread spectrum signal containing a number of equal amplitude spectral components.

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 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 ...

Spectrum efficiency of spread spectrum systems

IEEE 1988 International Symposium on Electromagnetic Compatibility, 2003
The capabilities of direct-sequence pseudo-noise (DSPN) systems are compared with those of both conventional and trunked LMR systems. It is shown that not only do DSPN systems provide the same advantages over conventional systems as trunking systems, but also they provide many additional features as well without loss of spectrum conservation. >
