Design and performance analysis of multicarrier M-ary differential chaos shift keying system

Abstract

The traditional differential chaotic keying (DCSK) system is a kind of low-power and low-complexity system. However, in order to meet the demand of high throughput of low-power network, like wireless body area network (WBAN), the DCSK system must be redesigned. A multicarrier M-ary differential chaos shift keying system(MC-MDCSK) has been proposed, where good diversity gain and high throughput have been achieved. Analytical bit-error-rate expressions are derived and verified by simulations over additive white Gaussian noise and multi-path fading channels.
