AI Technical Summary

Problems solved by technology

But the design engineering of its sampling system is poor
The window function used in the process of windowing and modulating the signal in the analog domain is complex, and its implementation cost is high and the clock requirement is high, which cannot be realized in the form of a simple filter similar to MWC
Non-deterministic measurement matrix is ​​difficult to engineer in practical applications, especially in multi-channel conditions

Abstract

The invention discloses a time domain modulation filter design method based on an exponential regenerative window and a filter, and relates to the technical field of filters. The filter designed by the method has an extremely simple time domain modulation function in the form of an exponential function. In order to further improve achievability, a process of multiplying the signal modulated in the frequency domain by the time domain modulation function and then performing integration is equivalent to an exponential filter, thereby achieving easy implement.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a design method of a time-domain modulation filter based on an exponential regeneration window and the filter. Background technique [0002] The under-Nyquist sampling technology of narrow pulse signal with finite time length is a research hotspot at home and abroad in recent years, and it has a wide range of applications in many fields such as radar and ultrasonic detection. For such signals, Ewa Matusiak and Yonina C.Eldar of Technion-Israel Institute of Technology proposed a theoretical model based on the Gabor framework for Nyquist sampling and reconstruction of narrow pulse signals based on the Gabor sampling principle, which can reduce the sampling rate to the duration of transient signals. Time is divided by one, and the number of sampling channels is reduced by using Compressed Sensing (CS) theory, which has important theoretical significance. But the design engineering ...
