Abstract
In this paper, we propose a complexity reduced spectrum sensing scheme for Bluetooth to
avoid the interference from 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. Finally, the performance of
the proposed scheme is verified by computer simulation in the presence of WLANs in the ISM band.
