Abstract
With the rapid development of modern communication technology, software-defined radio (SDR) technology has garnered significant attention in the field of electronic information engineering due to its flexibility and scalability. This study aims to explore the core principles of SDR technology and its potential in practical applications by analyzing its architectural design, signal processing methods, and strategies for hardware-software co-optimization, thereby addressing the issues of strong hardware dependency and poor adaptability in traditional communication systems. A combination of theoretical modeling and experimental validation was employed to construct an SDR system based on a general-purpose hardware platform. Innovative solutions were proposed for key challenges such as spectrum sensing, multi-standard compatibility, and dynamic resource allocation. The results demonstrate that the proposed system fr amework can substantially improve spectrum utilization, reduce hardware costs, and enable seamless switching between multiple communication standards. Furthermore, this research developed a set of efficient digital signal processing algorithms, which further enhanced the system's real-time performance and reliability. Overall, this study not only provides critical insights for the practical deployment of SDR technology but also lays a solid foundation for its extensive application in 5G and future communication networks, highlighting the immense potential of this technology in advancing the intelligence and efficiency of communication systems.
