Method and receiving set for implementing impulse ultra-wideband signal burst sampling

The invention relates to a method and a receiving device for realizing burst sampling of pulse ultra-wideband signal, wherein the method includes the following steps: an IR-UWB signal is divided into two parts with one part input to a signal delay unit and the other part input to an energy detecting unit; when the energy detecting unit detects that an IR-UWB pulse exists in the signal, a system control unit starts an analog-digital signal converter to complete sampling of the output signal of the signal delay unit; when no IR-UWB pulse is detected, the system control unit temporarily stops the sampling of the output signal of the signal delay unit by the analog-digital signal converter; the system control unit takes the duration of the second control signal generated by the energy detecting unit as the time interval of adjacent IR-UWB pulses, and inputs the duration to a digital signal processing unit; according to the signal and pulse duration parameters obtained by the analog-digital signal converter through sampling, the digital signal processing unit restores the transmitted information. The method saves power and improves system performance.
