FPGA Spread Spectrum Communication Method Based on M Sequence
2021 3rd International Conference on Intelligent Control, Measurement and Signal Processing and Intelligent Oil Field (ICMSP), 2021As an important digital communication technology, spread spectrum communication has the characteristics of strong anti-interference and high spectrum utilization, and has been widely used in real life. At the same time, because FPGA has the advantages of

Ultra-broadband chirp spread spectrum communication in the terahertz band
Defense + Commercial Sensing, 2020Terahertz (THz) band (0.1-10 THz) communication is envisioned as a key wireless technology to support faster and denser wireless networks. However, absorption by water vapor molecules splits the THz band into multiple transmission windows, each tens to ...

Performance Criteria for Spread Spectrum Communications
IEEE Transactions on Communications, 1977The 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 ...

IEEE Journal on Selected Areas in Communications
Achieving secure communication with a low probability of detection (covertness) is critical yet challenging, particularly when employing practical digital modulations that can compromise the statistical indistinguishability assumed in theoretical models.

Spread-spectrum communications
IEEE Potentials, 1993The 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, 2010We 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.
