Abstract

The invention relates to a compressed sampling based estimating method of the arrival time of pulse ultra-wide band signals, comprising a pulse ultra-wide band signal compressed sampling receiving system. The pulse ultra-wide band signal compressed sampling receiving system comprises a multichannel parallel sampling unit, a measuring waveform generator and a digital rear-end processing assemble, wherein the multichannel parallel sampling unit samples the pulse ultra-wide band signals through multiple channels; the measuring waveform generator respectively sends measuring waveforms to the channels of the multichannel parallel sampling unit; the digital rear-end processing assemble receives measured values sampled by the multichannel parallel sampling unit; and the channels respectively carries out linear projection on the pulse ultra-wide band signals according to measuring waveforms generated by the measuring waveform generator. The estimating method comprises the following steps of: determining projection interval; acquiring a sampling sequence; and acquiring the estimation of the arrival time. The invention obtains the high-accuracy TOA (Time Of Arrival) estimation from the compressed sampling sequence with low speed.

Description

technical field [0001] The invention relates to a method for estimating the time of arrival of a pulse ultra-wideband signal, in particular to a method for estimating the time of arrival of a pulse ultra-wideband signal based on compressed sampling. Background technique [0002] The task of time of arrival (TOA, time of arrival, TOA for short) estimation is to detect the direct path DP (direct path, direct single path, short for "DP") center from the sampling sequence of the ranging received signal. where the sampling point is located. According to the different sampling rates and receiver hardware capabilities, the existing TOA estimation algorithms can be roughly divided into two categories: coherent TOA estimation algorithms and non-coherent TOA estimation algorithms. If the receiver's hardware capability is sufficient (can provide local templates and ensure high sampling rate), and the computing capability is strong, the coherent TOA estimation algorithm can be used; if...
