Cognitive radio communication system based on hardware platform and relevant quiet period research thereof

摘要

when a cognitive radio system is designed, one of the key technologies for establishing the radio system is that cognitive nodes cognize other surrounding ones. For this reason, a thorough research for perception and detection methods is regarded as one core part of the cognitive radio quiet period research. The text focuses on the design and research of the system without the quiet period, and analyzes performance simulation processes and results during the radio quiet period, thus the text has strong scientific nature and reasonability.
