AB - From the spectrum utilization point of view, an M-ary modulation scheme
is sometimes preferred over a binary one because more data can be transmitted in the
same bandwidth. In this paper, we propose an M-ary chaotic-sequence spread-spectrum
modulation scheme. In this scheme, each block of chaotic sequence produced by a chaotic
map undergoes a transformation before it is transmitted. At the receiver, based on the block
of chaotic sequence received, the appropriate inverse transformation is performed, and the
received symbol is decoded. A permutation-based transformation process is proposed, and
a simple method to construct the permutations corresponding to different symbols is also
presented. Coherent and noncoherent systems are investigated, and their performances are
studied by computer simulations.
