Novel Spread Spectrum Communication Theory and the Anti-jamming Applications

In modern engineering practice, a random sequence is widely used in information security, cryptography, automatic control, digital communication, radar, acoustic and optical measurement, and fault detection of the digital network system, etc. Chaos is a nonlinear dynamic system, a kind of always confined to a limited area, and orbit is never repeated, characteristic of complex movement. Because the chaotic system has extreme sensitivity to initial condition and control parameter and major features such as wide frequency spectrum, class random this to produce the high-performance random sequence model provides optimal research. Under this background, a novel spread-spectrum communication theory and the anti-jamming applications were proposed. To extend the emission signal spectrum, use different techniques for the preaching of information processing, result in modern different types of spread spectrum modulation. Due to the simple of jump anti-jamming is not strong, rarely used alone. Jump is usually combined with another method of all kinds of mixed-mode. The enhanced model is applied to the general application of anti-jamming. The experiment verifies the feasibility and robustness of the proposed framework compared with other methodologies.
