A 7.4mW 200MS/s Wideband Spectrum Sensing Digital Baseband Processor for Cognitive Radios
Abstract
| A 65nm CMOS spectrum sensing digital baseband processor for cognitive radios is integrated in 1.64mm2. The processor achieves detection probability ≥ 0.9 and false-alarm probability ≤ 0.1 for the -5dB SNR regime within a 50ms sensing time. The chip dissipates 7.4mW for a 200MHz radio bandwidth. A 22x power reduction per sensing bandwidth is achieved compared to state-of-the-art designs. |
