摘要:In the cognitive radio (CR) systems the total scanning time that is the time taken by the receiver to sense the spectrum is one of the issues in perspective of the overall system performance. This paper proposes architecture for a dedicated receiver capable to reduce sensing time with using dual part: the main receiver and a dedicated one, each with multiple antennas (M). The achieved results show that the total sensing time is reduced by approximately 1/M with using the proposed structure.
