“…In [14], [86], and [97]- [102], the authors analysed the correlation properties and the synchronization performances of the quantified version of chaotic signal. Moreover, they designed new binary chaos-based sequence and they showed that when particular chaotic generators are used the expected performance is not worse than that of a well-behaving communications system [101], [103]- [105].…”

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.

“…On the other hand, the real values of chaotic sequences were analysed under various scenarios [5], [6], [102], [106]- [111]. Correlation properties were studied [106]- [109] and some designed chaotic sequences were proposed [110]- [112] and used to optimize the error performance of the communication system.…”

“…The main challenge with chaotic DSSS resides in code generation [77]. Reliable electronic hardware implementations of chaotic sequence generators based on recursion of maps by linear analogue functions are currently impossible owing to the manufacturing difficulties [78]. Fortunately, several modified and alternative approaches based on digital nonlinear functions were proposed and proved to have satisfying performances [79].…”

Unmanned combat aerial vehicles (UCAVs) that swarm with both autonomous decision-making and cooperative attacking have been regarded as revolutionary elements of modern warfare. In such a swarm, inter-group connectivity must be ensured in a network to maintain a collective consensus. In recent years, academia and industry have made many efforts to achieve common tactical data link systems and commercial drone networks. However, the existing results have difficulty meeting the needs of cooperative autonomous UCAV swarms with both hypersonic mobility and time sensitivity in severe confrontation scenarios. In this article, we conduct an in-depth investigation of the network used for the hypersonic UCAV swarms, which can be considered as a special form of mobile wireless network. Furthermore, faced with specific functional demands, we summarize the main challenges of designing this dedicated network. In addition, a comprehensive survey of potential solutions for the network design is presented. Lastly, we discuss the possible capabilities of the network given the current forefront of technology, as well as remaining challenges and open issues.

“…In turn, Drake and Williams [10] studied a dynamical system based on the sawtooth map to produce pseudo-chaotic sequences applied to a direct-sequence SS communication system. Later on, Wang and Hu [11] proposed the logistic map to generate the PN sequence while Leon et al [12] exploited the quantization of chaotic maps. Besides, there have been some efforts to analyze the properties of this kind of sequences, for example Xia and collaborators [13] analyzed chaotic binary sequences and their application to code division multiple access (CDMA) systems.…”

Dynamical systems methods have been recently used in spread-spectrum digital communication systems. Theexpansion of the spectrum using a pseudorandom sequence with a higher frequency than the information signal is thekey feature for its robustness against the signal traveling interference through the channel. In this work, we propose togenerate pseudorandom sequences by employing cellular automata and we check these sequences have thenecessary properties which are required in modern communication systems. The computed sequences obtained bythe cellular automata are tested in a quadrature phase shift keying (QPSK) spread-spectrum communication system.The efficiency of the system is analyzed by computing the bit error rate under different signal to noise ratio conditions.These results are compared with systems that employ Golden code and other typical pseudorandom sequences.
