Cognitive Radio Integration in MIMO Systems for Dynamic Spectrum Access and Management

Cognitive Radio (CR) technology has emerged as a promising solution to the increasing demand for efficient spectrum utilization, addressing the challenges posed by the limited availability and inefficient use of the radio frequency spectrum. This research delves into the integration of CR with Multiple Input Multiple Output (MIMO) systems, aiming to enhance dynamic spectrum access and management capabilities. By leveraging the spatial diversity inherent in MIMO systems, the combined architecture offers improved spectrum sensing, adaptive transmission, and interference mitigation. The study presents a comprehensive framework for the coexistence of primary and secondary users, ensuring minimal interference while maximizing spectral efficiency. Advanced algorithms are proposed for spectrum sensing and allocation, considering the spatial and temporal characteristics of the wireless environment. Performance evaluations, based on extensive simulations, demonstrate significant gains in terms of throughput, latency, and reliability when compared to traditional MIMO or standalone CR systems. The findings underscore the potential of integrating CR with MIMO as a viable approach to address the ever-growing demands of modern wireless communication systems.
