Chaotic sequences are effectively used for secure communication. Generation of chaotic sequences continues to be an evolving area. Recently, stress has been given to the generation of orthogonal chaotic codes. In this paper, a chaotic spreading sequence based Direct Sequence/Spread Spectrum (DSSS) communication system is proposed. Here, a logistic map is used for generation of chaotic sequences used as a spreading factor in a DSSS system in Rayleigh fading channel. The authors discuss a method to make the chaotic code orthogonal to mitigate several disadvantages of the channel.
