Abstract

Over the past decade, much research effort has been devoted to the study of communication using chaotic basis functions. Due to the low complexity in hardware implementation and low power consumption in chaotic signal generation, the chaotic signal is one of the possible candidate signals, applicable to both low rate Ultra-WideBand (UWB) systems and sensor networks. Among the modulation schemes using the chaotic signal, Differential Chaos Shift Keying (DCSK) is a robust non-coherent technique with respect to the implementation issue. However, Inter Symbol Interference (ISI) can induce the crucial performance degradation and synchronization error may destroy the orthogonality of the basis functions. Therefore, we present enhanced DCSK scheme and investigate the effect of the synchronization error on the performance by comparison with that of conventional DCSK.
