[TR16] Very High Efficiency Differential Chaos Shift Keying System
Revue Internationale avec comité de lecture : Journal IET Communications, vol. To appear, pp. pp, 2016Mots clés: DCSK, VHE-DCSK, spectral efficiency
Résumé:
In this paper, a new noncoherent communication system, i.e. very high efficiency differential
chaos shift keying system (VHE-DCSK), is proposed. This system is a generalized form
of the high efficiency differential chaos shift keying system (HE-DCSK), with an arbitrary number
(N) of transmitted bits per frame. The major advantage of this new proposition is its ability
to significantly improve the spectral efficiency compared to DCSK and HE-DCSK. The theoretical
bit error rate (BER) of this system is found using the Gaussian approximation method under
different communication channels: additive white Gaussian noise (AWGN) and two-ray Rayleigh
fading channels. Simulations in both environments show a perfect match with the analytical expressions
for large spreading factors. Simulations results for the two-ray Rayleigh fading channel
show clearly the diversity gain compared to the single-ray Rayleigh channel.
