报告摘要：
Cognitive radio has been considered as a promising technology to improve the spectrum utilization efficiency in wireless communications. There are a lot of research and development activities on cognitive radio in the past ten years. In this talk, I will first provide an overview on various research topics in this area, then highlight, though the full picture of cognitive radio may take long time to realize, several cognitive radio concepts are now actively developed in various wireless systems, such as femtocell networks, carrier aggregation in LTE-A, and TD-LTE in TV white spaces. I will also share some views on future directions of cognitive radio research and developments.
