“…Since the structure of the DCSK system is simple and its performance is well, the DCSK scheme and its variants have been studied for more than 10 years [2][3][4]. Moreover, they are more feasible in practice implementation [5,6]. In a DCSK system, one bit duration is divided into two equal slots.…”

An exact method is employed to analyze the bit error rate (BER) performances of differential chaos shift keying (DCSK) communication system over fading channels. The exact BER performances of DCSK in Nakagami-m Rayleigh and Rician fading channels are derived, respectively. The Gaussian approximation (GA) method is compared with the exact method. The numerical results and simulation results for the two methods are presented and are compared in the fading channels, respectively. These results support our theoretical analysis.

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.

“…A hardware implementation of such system was demonstrated [24]. Chaos shift keying (CSK) methods have been explored for secure communication [27,28]. The communication system using chaotic modulation scheme called modified differential chaos shift keying was implemented in 0.25-μm CMOS technology [27].…”

In the last decade and so, a large amount of research has been done to secure hardware. Security features such as physically unclonable function (PUF), hardware metering, and obfuscation have been developed to protect hardware from threats. Detection and avoidance techniques for IC counterfeiting and hardware Trojan have been introduced to protect the IC supply chain. Till now, research has focused on digital ICs, but analog and mixed signal (AMS) ICs which hold the highest share in the market have been neglected. The solutions developed in digital domain for digital ICs do not extend well to AMS ICs. Thus, a major portion of the IC market remains unsecured. In this paper, we described the challenges and limitations associated with AMS IC security research focusing on three major sections: AMS-enabled security, counterfeiting, and AMS hardware Trojans. We also express a vision for AMS security research.
