“…Note that, again, the numerical evaluation of the analytical BER captures the behavior of the experimental data: the advantage of the former from the point of view of the analysis and design is that the calculations involved are less time and resource consuming than the ones usually devoted to a standard simulation.

“…Another scheme was proposed by the same authors in [32]: a correlation delay-shift-keying (CDSK) system where the reference and data sequences are transmitted simultaneously in order to increase the data rate and security, but at the cost of a bit-error rate (BER) performance loss. In [33], a multiresolution M-ary DCSK system is proposed, making it possible to manage the tradeoffs of BER and quality of service while keeping the properties of DCSK.…”

Abstract-Conventional Differential Chaos-Shift-Keying systems (DCSK) are not the most suitable for supporting continuous-mobility scenarios. Therefore, in this paper an improved Continuous-Mobility Differential Chaos-Shift-Keying system (CM-DCSK) is presented that provides greater agility and improved performance in fast fading channels without accurate channel estimation while still being simple compared to a conventional DCSK system. A new DCSK frame signal is designed to reach this goal. In our new frame design, each reference sample is followed by a data carrier sample. This modification of the system design reduces the hardware complexity of DCSK because it requires a shorter wideband delay line, and significantly improves the performance over fast fading channels while keeping the noncoherent nature of the transmission system. Once the design is explained, the bit error rate performance is computed over a multipath fast fading channel and compared to the conventional DCSK system. Simulation results confirm the advantages of this new non-coherent spread-spectrum design that can support mobility.

“…Compared to QCSK, the proposed OCVSK increases data transmission rates with greatly improved robustness. Recently, L. Wang et al proposed in [180] a new multiresolution (MR) M -ary differential chaos shift keying (DCSK) modulation scheme as extension to the QCSK scheme. The authors showed in this work that this new system provides better anti-multipath fading performance against various spreading factors, which inherits the advantages of the conventional DCSK system.…”

Since the early 1990s, a large number of chaos-based communication systems have been proposed exploiting the properties of chaotic waveforms. The motivation lies in the significant advantages provided by this class of non-linear signals. For this aim, many communication schemes and applications have been specially designed for chaos-based communication systems where energy, data rate, and synchronization awareness are considered in most designs. Recently, the major focus, however, has been given to the non-coherent chaos-based systems to benefit from the advantages of chaotic signals and noncoherent detection and to avoid the use of chaotic synchronization, which suffers from weak performance in the presence of additive noise. This paper presents a comprehensive survey of the entire wireless radio frequency chaos-based communication systems. First, it outlines the challenges of chaos implementations and synchronization methods, followed by comprehensive literature review and analysis of chaos-based coherent techniques and their applications. In the second part of the survey, we offer a taxonomy of the current literature by focusing on non-coherent detection methods. For each modulation class, this paper categorizes different transmission techniques by elaborating on its modulation, receiver type, data rate, complexity, energy efficiency, multiple access scheme, and performance. In addition, this survey reports on the analysis of tradeoff between different chaos-based communication systems. Finally, several concluding remarks are discussed.

“…Starting by the early work of [20] in which a quadratic chaos shift keying QCSK is proposed, which uses the Hilbert transform to generate orthogonal bases of chaotic functions in order to allow the transmission of more bits with respect to conventional DCSK while demanding an equal amount of bandwidth and finishing by the multi-resolution M-ary DCSK scheme of [21], there has been a series of serious efforts to outstrip the shortages of DCSK.…”

Abstract-Data rate and energy efficiency decrement caused by the transmission of reference and data carrier signals in equal portions constitute the major drawback of differential chaos shift keying (DCSK) systems. To overcome this dominant drawback, a short reference DCSK system (SR-DCSK) is proposed. In SR-DCSK, the number of chaotic samples that constitute the reference signal is shortened to R such that it occupies less than half of the bit duration. To build the transmitted data signal, P concatenated replicas of R are used to spread the data. This operation increases data rate and enhances energy efficiency without imposing extra complexity onto the system structure. The receiver uses its knowledge of the integers R and P to recover the data. The proposed system is analytically studied and the enhanced data rate and bit energy saving percentages are computed. Furthermore, theoretical performance for AWGN and multipath fading channels are derived and validated via simulation. In addition, optimising the length of the reference signal R is exposed to detailed discussion and analysis. Finally, the application of the proposed short reference technique to the majority of transmit reference systems such as DCSK, multicarrier DCSK, and quadratic chaos shift keying enhances the overall performance of this class of chaotic modulations and is, therefore, promising.
