A Comprehensive Study of Past, Present, and Future of Spectrum Sharing and Information Embedding Techniques in Joint Wireless Communication and Radar Systems

Wireless spectrum is a limited resource, and the rapid increase in demand for wireless communication-based services increasing day by day. Hence, maintaining good quality of service, high data rate, reliability need Thus, we to apportion available an efficient manner. Dual-Function Radar Communication (DFRC) emerging field bears vital importance both civil military applications last few years. Since hybridization communication radar designs provoke diverse challenges, e.g., interference mitigation, secure mobile communication, improved bit error rate (BER), enhancement without compromising performance, this paper reviews state-of-the-art developments shared between radars terms coexistence, collaboration, cognition, cooperation. Compared existing surveys, explore open research issue on operating with mutual benefits based collaboration sharing. Additionally, provides important perspectives future DFRC technology.
