Abstract

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.
