Spectrum Occupancy Measurement:Focus on the TV Frequency
Dynamic spectrum access to the unused licensed spectrum has been proposed as a solution to the spectrum scarcity problem. However, efficient spectrum sensing techniques are crucial on the way towards systems, which use idle spectrum bands opportunistically and increase the overall spectral efficiency. The spectrum occupancy measurement is very important for the efficient spectrum sensing. Current spectrum occupancy was evaluated in few measurement campaigns. This paper describes spectrum occupancy measurement about TV spectrum source performed in Chengdu. Through analysis measurement result, we can find the idle spectrum band which can be used by the Cognitive Radio.
