A finite rate of innovation multichannel sampling hardware system for multi-pulse signals

Ning Fu, Liwen Sun, Guoxing Huang, Shuaile Du

ICASSP 2017accepted

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, os…

Sparsity-based reconstruction method for signals with finite rate of innovation

Guoxing Huang, Ning Fu, Jingchao Zhang, Liyan Qiao

ICASSP 2016accepted

In the last decade, it was shown that it is possible to reconstruct signals with finite rate of innovation (FRI signals) from the samples of their filtered versions. However, when noise is present, the present reconstruction algorithms tend to be low accuracy. In this work, a new sparsity-based reco…
