Abstract

Pulse ultra-wideband technology uses narrow pulse as the information carrier, occupies a very wide frequency bandwidth, and has many characteristics such as high transmission rate, large capacity and strong multipath resistance. Chaotic signals are stochastic and sensitive to initial values, so they are widely used in secure communication systems. In this paper, the chaotic sequence of quadratic chaotic map is generated by matrix method. The new digital chaotic sequence after binary quantization is applied to the direct sequence spread spectrum UWB system. It reduces the influence of quantization on the randomness and ameliorates the dispersion of UWB signals power spectrum, making the interference with other systems lower. The simulation shows that the chaotic direct sequence spread spectrum UWB system based on chaotic matrix quadratic mapping has better system coexistence.
