Robust chaotic PN sequence generation techniques

A novel chaos based pseudo-noise (PN) sequence generation technique is presented. This technique is based on the direct quantization of chaotic maps, which guarantees the generation of repeatable sequences based only on the initial condition. A cell based sequence generator architecture based on the presented approach has been developed and implemented as a prototype integrated circuit. The simulation and test results shown that a very large space of PN sequences with desirable statistical properties for spread spectrum communication systems can be generated in a robust, scalable, and programmable manner.
