  The chaotic systems have been found applications in diverse fields such as
pseudo random number generator, coding, cryptography, spread spectrum (SS)
communications etc. The inherent capability of generating a large space of PN
sequences due to sensitive dependence on initial conditions has been the main
reason for exploiting chaos in spread spectrum communication systems. This
behaviour suggests that it is straightforward to generate a variety of initial
condition induced PN sequences with nice statistical properties by quantising
the output of an iterated chaotic map. In the present paper the study has been
carried out for the feasibility and usefulness of chaotic sequence in SS based
applications like communication and watermarking.
