摘要：

This paper proposes the scheme of the out-of-band cooperative spectrum sensing in the cognitive radio (CR) base station to be operated by the multiple spectrum bands. And it suggests signal detection results for the ATSC TV signal as an incumbent signal, and derives signal detection probability and false-alarm probability for the out-of-band cooperative spectrum sensing in the frequency selective Rayleigh fading channel. Numerical results demonstrate that sensing performance for the incumbent signal is improved by the out-of-band cooperative spectrum sensing in case the power strengths of the incumbent signal to be measured by the CR users of the multiple channels are almost similar.
