Abstract
In this brief, a phase-separated differential chaos shift keying (PS-DCSK) modulation scheme is proposed as a simple delay-component-free version of DCSK modulation. Separated by orthogonal sinusoidal carriers rather than time delay, the reference and information-bearing signals in DCSK are transmitted simultaneously and parallel in the proposed system. As a result, PS-DCSK not only can avoid the difficult-to-implement radio-frequency delay line problem but also can achieve a doubled attainable data rate, enhanced communication security, and equivalent bit-error-rate (BER) performance with respect to DCSK. Finally, analytical expressions for the BER performance of the proposed system are derived and verified by computer simulation results over additive Gaussian white noise and Rayleigh fading channels.
