MIMO and Chaotic Communication: Systematic Literature Review

Owing to its low power consumption during chaotic signal production and reduced hardware implementation complexity, chaotic communications have attracted attention in the field of wireless communications. To enhance system efficiency in wireless networks, multiple transmit and/or multiple-input multiple-output (MIMO) systems leverage several receive antennas. The system is made resilient by the combination of MIMO and chaotic communication signals, which increases data throughput, capacity, ease of installation, and secure communication. In this regard, this article employed a standardized systematic literature review method to conduct a critical analysis of the selected papers. The study aimed to highlight the advantages of combination of MIMO and chaotic communication in enhancing the security of physical layer. The review selected and analyzed recent research papers disseminated between 2007 and 2023 and a total of 30 papers were reviewed. The review carried out a detailed evaluation of the selected papers with regard to the modulation techniques, channel coding techniques etc. The article concludes by highlighting the possible research directions preferred reporting items for systematic reviews and meta analyses (PRISMA) framework are used. Overall, this article provides a comprehensive summary of key improvements in enhancing the security through the use of MIMO and chaotic communication. However, there is no specific literature review article on combination of MIMO and chaotic communication.
