FPGA IMPLEMENTATION OF DIRECT SEQUENCE SPREAD SPECTRUM TRANSMITTER WITH PSEUDO CHAOTIC GENERATOR.

Chaos based pseudo noise sequences for spread spectrum communications ranks amongst the most promising applications of chaos to communication. In arriving at these new sequences the theory of chaos has been used. The correlation properties of these chaotic sequences are analogous to white noise. In this paper we describe FPGA implementation of a spread spectrum transmitter using pseudo-chaotic sequences (PCS) for spreading the input digital data. The lengths of chaotic sequences are not restricted like LFSR sequences. The generated pseudo-chaotic sequences are investigated for autocorrelation, cross- correlation and balance properties.
