Abstract :
A digital baseband cognitive radio spectrum sensing with channel-specific threshold and sensing time is integrated in 1.64mm2 in 65nm CMOS. The processor achieves detection probability ≥ 0.9 and false-alarm probability ≤ 0.1 for -5dB SNR within a 50ms sensing time. The chip dissipates 7.4mW for a 200MHz sensing bandwidth. A 22x reduction in power per sensing bandwidth is achieved compared to prior work.
