Co-existence of chaos-based and conventional digital communication systems

This paper studies the performance of selected chaos-based communication systems whose spectrum overlaps with that of conventional narrowband systems. Such a scenario may occur in normal practice when chaos-based systems are introduced while the conventional systems are still in operation. The particular chaos-based systems under study are the coherent chaos-shift-keying (CSK) system and the non-coherent differential CSK system, and the coexisting conventional system employs the binary phase-shift-keying modulation scheme. Analytical expressions for the bit error rates are derived and computer simulations are performed to verify the analytical findings.
