Outline of Final Research Achievements

With the extremely increasing of mobile data traffic, there is a common belief that we are facing a severe shortage of spectrum resource for wireless communications in the near future. On the other hand, the spectrum utilization ratio is extremely low due to the spectrum resource is exclusively used by different systems. In this research, we propose a crowdsourcing based spectrum database to improve the spectral utilization of the whole system.
