Title: | A square-constellation-based M-ary DCSK communication system | Authors: | Cai, G Fang, Y Han, G Lau, FCM Wang, L |
Issue Date: | 2016 | Source: | IEEE access, 2016, v. 4, p. 6295-6303 | Abstract: | In this paper, a square-constellation-based M-ary differential chaos-shift-keying (M-DCSK) communication system framework is proposed. The symbol-error-rate expression of the proposed system is derived over additive white Gaussian noise as well as multipath Rayleigh fading channels. Moreover, the peak-to-average-power-ratio (PAPR) performance is carefully analyzed for the newly proposed system. Based on the square-constellation-based M-DCSK framework, a simple least-square estimator is designed to demodulate the information exploiting pilot-assistant symbols. Analytical and simulated results show that the proposed system benefits from a lower energy consumption, but suffers from a higher PAPR compared with the circle-constellation-based M -DCSK system. | Keywords: | M-ary differential chaos-shift-keying (M-DCSK) Multipath Rayleigh fading channel Peak-to-average-power ratio (PAPR) Symbol error rate |
