Title
A 3.1-10.6GHz wavelet-based dual-resolution spectrum sensing with harmonic rejection mixers.
Abstract
A triple-channel wavelet-based dual-resolution spectrum sensor fabricated with 1V 65nm CMOS technology provides 3.1-10.6GHz range of spectrum sensing bandwidth with < 6.4mW/GHz efficiency. Dual-resolution cooperative sensing with two adjacent channels eliminates fine detection process, which leads to < 0.4msec of total sensing time. The spectrum sensor achieves the minimum detection sensitivity of -75dBm and out of band rejection of <-45dBc by exploiting triangular wavelet with LPF. 3.1-5GHz harmonic rejection mixers suppress third harmonic to -32dBc. Die area is 2.75mm(2) with on-die PLLs.
