  Abstract

Recently, many cognitive radio schemes have been proposed due to the development of wireless communication technology and increasement of the number of wireless devices. Therefore, many USRP-based cognitive radio testbeds have been proposed to analyze the schemes in a real-world. However, they do not provide any criteria for setting sensing time of the secondary user. In this paper, how to measure the sensing time limit to guarantee the performance of the secondary user in a USRP-based cognitive radio testbed is described. First of all, the architecture of the cognitive radio testbed and the experimental method and results will be described. The sensing time can be a clear criterion for setting the sensing time in future cognitive radio related studies.
