Fast Multiband Spectrum Scanning for Cognitive Radio Systems.
IEEE Transactions on Communications(2013)
摘要
This paper considers the problem of how to quickly and accurately determine the availability of each spectrum band for a multi-band primary system using one or few sensors. Such problem is referred to as spectrum scanning. Two cases of practical interest are studied: 1) a single sensor case in which only one spectrum band is observed at one time; and 2) a multiple sensor case in which multiple spe...
