dc.description.abstractIn this paper, we propose a complexity reduced
spectrum sensing technique for Bluetooth to find channels free
from the use of other communication devices in 2.4 GHz ISM
band. By exploiting the spectrum characteristics of interference
sources, the proposed scheme detects the availability of channels
by comparing the power spectrum density (PSD) with a
threshold. To reduce the implementation complexity, the PSD
is calculated by means of fast Fourier transform and linear
interpolation. The threshold for the detection is determined to
maximize the detection probability. To further improve the transmission
performance, the proposed scheme dynamically changes
the channels by measuring the transmission performance.
