Abstract

The invention relates to a compressively sampling and receiving system for impulse ultra-wideband signals, which is characterized by comprising a multichannel sampling unit for distributing a plurality of channels for the impulse ultra-wideband signals to perform parallel sampling, a measuring waveform generator for respectively sending measuring waveforms to channels of the multichannel sampling unit, and a digital rear-end receiving processing unit for receiving measured values sampled by the multichannel sampling unit. The impulse ultra-wideband signals are continuous multiframe signals; the measuring waveforms generated by the measuring waveform generator are irrelevant to impulse ultra-wideband receiving signals which enter the multichannel sampling unit; the channels respectively linearly project the impulse ultra-wideband receiving signals according to the measuring waveforms generated by the measuring waveform generator; and the digital rear-end receiving processing component processes the measuring values sampled by the multichannel sampling unit. The compressively sampling and receiving system for the impulse ultra-wideband signals does not require high sampling speed, long delay line or exact channel estimation, and can fully exploit the potential of the high-speed communication and the high-precision distance measurement of the Infrared Radiation-Ultra Wide Bandwidth (IR-UWB).

Description

technical field [0001] The invention relates to a compressed sampling receiving system and method for pulsed ultra-wideband signals, in particular to a low-speed sampling receiving system and method for pulsed ultra-wideband signals oriented to short-distance wireless communication applications. Background technique [0002] The traditional IR-UWB (Impulse Radio-Ultra WideBand, "IR-UWB" for short) signal receiving schemes include: full-resolution digital receiver, analog correlation receiver, Rake receiver, and energy detection receiver. They are described as follows: [0003] Full Resolution Digital Receiver [0004] Sampling the received signal with filtered out-of-band noise at the Nyquist rate or even a higher rate, and all subsequent processing tasks are based on high-resolution sampling of the output of the ADC (Analog to Digital Converter, “ADC” for short) sequence processing. The advantages of this receiving method are high flexibility, simple structure, easy conf...
