A CMOS Energy-Detector for Impulse-Radio UWB Noncoherent Receivers
Impulse-Radio Ultra-WideBand (IR-UWB) has recently become one of the most inspiring technologies for a great diversity of emerging wireless applications. IR-UWB relies on the transmission of sub-nanosecond pulses with reduced amplitudes. Due to the broadband spectrum of short-pulse waveforms, the susceptibility against multipath fading is strongly reduced, which fits common requirements of most modern indoor short-range applications. Moreover, IRUWB interfaces allow the implementation of low-cost/low-power solutions well-suited to the typical purposes of some emerging applications, such as wireless sensor networks and biomedical implants.
