The new communication networks are expected to support the growing demands for wireless services with critical requirements of high connectivity, spectral efficiency, reliability, and information security. Therefore, nonorthogonal multiple access (NOMA) strategy has been adopted as a key component to fulfill the main targets of 5G systems. On the other hand, varied chaotic communication systems have been introduced for robust and cost-effective physical layer security. This paper presents a condensed survey on the existing chaos-based communications and NOMA schemes with their important features and applications. Then, the investment of chaotic signals in NOMA is highlighted as a promising wireless nonorthogonal chaotic communication (WNCC) technology. An insightful vision on the possible opportunities of WNCC schemes based on code and/or power domains is presented and verified by the available findings and one of our preliminary paradigms to demonstrate the extended connectivity with desired security. Moreover, the major challenges and practical considerations for WNCC systems are discussed and followed by some avenues for future research directions.

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.

“…In the last 15 years, many coherent and non-coherent chaosbased communication systems have been studied and inspected [7], [11]- [17]. Conventional differential chaos shift keying (DCSK) [2], [13], [16]- [18] is one of the most examined systems amid chaos-based communication systems simply because neither chaotic synchronisation nor channel state information is a requirement at the receiver side to generate the required chaotic replica.…”

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.
