Abstract

Novel approaches to pseudo-noise (PN) sequence generation are presented and applied to spread spectrum communications. These approaches exploit the direct quantisation of chaotic maps, which results in fully digital implementations of pseudo-chaotic sequence generators. The robust digital implementation eliminates the variation tolerance and electronic noise problems common in analogue chaotic circuits. A cell based sequence generator architecture has been developed and implemented as a prototype integrated circuit. The architecture exhibits sensitive dependence on initial conditions and is capable of generating a new class of pseudo-chaotic sequences. The simulation and test results indicate that distinct sequences suitable for spread spectrum communication systems can be easily generated in a robust, scalable and programmable manner using the presented approach.
