Spread-spectrum techniques for wireless communication

IEEE Signal Processing Magazine, 1997
The primary goal of this paper is to provide a concise introduction to the use of spread spectrum in wireless communications. The symbiotic relationship between wireless communications and digital microelectronics is also developing rapidly. Indeed, mobile and personal communications is now at parity with the computer industry as a major driver in the ...

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 ...

Spread spectrum for commercial communications

IEEE Communications Magazine, 1991
The authors describe how spread spectrum operates and explain why the FCC has allocated several spectral bands for spread spectrum. They examine what is wrong with the spectrum allocations the way they are now. They show who is using and will use spread spectrum and why.

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 ...

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.
