Multi-pulse signals are composed of finite pulse streams of arbitrary pulse shape. With the pulse shape known, a multichannel sampling scheme for multi-pulse signals can operate at the rate of innovation, which is much lower than the Nyquist rate. The sampling system is based on low-pass filters, oscillators and integrators. By now there is no hardware to practice the approach. In this paper, we design...
In order to improve the image reconstruction quality of electromagnetic tomography (EMT), a new EMT image reconstruction method based on finite rate of innovation (FRI) is put forward in this paper. The FRI sampling process is used to extract the feature information and combined a new measurement equation. Firstly, the conductivity distribution of the target object inside pipeline is modeled as an...
