Abstract:
Chaotic modulation has attracted much attention in the past two decades for low-power and low-cost wireless communication applications due to its excellent anti-fading capability. In this paper, we propose a new differential chaos shift keying (DCSK)-based system equipped with a novel automatic repeat request/cooperative automatic repeat request (ARQ/CARQ) technique, called as DCSK-ARQ/CARQ system. We also modify the receiver to implement the DCSK-ARQ/CARQ system. To conduct a more insightful study, we analyze the error performance and throughput of the proposed system over multipath Nakagami-m fading channels. Both the theoretical analyses and simulated results indicate that the DCSK-ARQ/CARQ system is remarkably superior to the existing DCSK non-cooperative/cooperative communication (DCSK-NC/CC) system. Moreover, the impact of various critical parameters on the system performance is discussed and optimized so as to facilitate the practical wireless applications.
