Abstract
This paper proposes a new database-based two-stage
channel selection method for cognitive radios. The
proposed method consists of two stages, namely the
database collection and signal detection parts. The
database collects information about channels. When a
cognitive radio needs to find an unoccupied channel for a
transmission, it sends a query to the database. Based on
the information collected to the database, the most
probably unoccupied channels at requesting time are the
best candidates when searching unoccupied channels, and
these channels are submitted to the cognitive radio. The
cognitive radio performs first the power level detection.
Based on the power level information delivered from the
database, a full signal detection is performed next to
the channel with low enough power level to ensure that
the channel is really unoccupied. (16 refs.)
