Conventional distributed cognitive radio (CR) communication aims to increase the sensing accuracy and reduce the detection time by allowing the CR users to operate in the same frequency band in a cooperative fashion and by forming efficient decision making. In this paper, we propose a spectrum sensing scheme which provides low complexity accurate detection by assigning different sensing tasks to the CRs. In our method, with N cooperative CRs, an effective sensing resolution of N times higher than that of a single CR is achieved. An inherently low complex reconfigurable progressive decimation filter bank is used at each CR. The hardware complexity of our sensing scheme is more than N times lower than that of the conventional spectrum sensor.
