“…We focus on Chaos Shift Keying (CSK) and its variants based on noncoherent or differential demodulation because of their promise in proposed practical applications (Kennedy, Kolumbán, Kis & Jákó, 2000;Kennedy, Setti & Rovatti, 2000;Kolumban et al, 1997;Kolumban, Kennedy & Chua, 1998;Lau & Tse, 2003;Stavroulakis, 2005). In fact, researchers from the Optical Communications Laboratory of the Athens University in Greece, implemented an 120km optical fiber link in metropolitan Athens and managed to transmit at gigabit rates using CSK (Argyris et al, 2005;Syvridis, 2009).…”

“…The DCSK communication scheme, which exploit the repetitive nature of the chaotic signal, extending from simple binary communications to more sophisticated detectors, have been discussed [8]. Multipath performance of binary DCSK systems using a standard correlation detector was discussed in [9]- [10]. Quadrature CSK (QCSK) is a multilevel version of DCSK, based on the generation of an orthogonal of chaotic functions.…”

In recent years, various chaos based modulation schemes were evolved, of which the CS-DCSK modulation technique provides better BER performance and bandwidth efficiency, due to its code domain approach. The QCSK modulation technique provides double benefit: higher data rate with similar BER performance and same bandwidth occupation as DCSK. By combining the advantage of code shifted differential chaos shift keying (CS-DCSK) and Quadrature chaos shift keying (QCSK) scheme, a novel CS-QCSK modulation scheme called code shifted Quadrature chaos shift keying is proposed. The noise performance of CS-QCSK is better to most conventional modulation schemes and also provides an increased data transmission rates with greatly improved robustness. Analytical expressions for the bit-error rates are derived for both AWGN channel and Rayleigh multipath fading channel. The simulation result shows that the proposed method outperforms classical chaotic modulation schemes in terms of bit error rate (BER).

“…From those systems, the DCSK one represents a robust non-coherent scheme in which the chaotic signal at the receiver side does not have to be known exactly. In addition, the DCSK system is one of the most promising chaos-based communications schemes for the robustness against channel imperfections [3].…”

Abstract-In this paper the first experimental chaos radio system using Differential Chaos Shift Keying is realized. The software design and implementation are proposed for the experimental Differential Chaos Shift Keying (DCSK) system on software defined radio (SDR) to perform in a real-time wireless transmission. The GNU Radio platform is used as a flexible and open-source platform for our implementation. In order to perform in real-time wireless scenarios, the proposed work implements a synchronization unit on the receiver side. Since our system is on a SDR, the bitrate, bandwidth and central frequency can be modified at ease. The experimental performance are discussed and compared to the theoretical predictions. Finally some trends concerning implementation are discussed.
