Abstract: We consider the problem of sampling signals which are comprised of pulse streams. This model belongs to the recently introduced framework of signals with finite rate of innovation. The minimal sampling rate for such signals is the number of degrees of freedom per unit of time, referred to as the rate of innovation. Although sampling of pulse streams was treated in various works, either the rate of innovation was not achieved, or the pulse shape was limited to diracs. In this work we propose multichannel schemes for arbitrary pulse streams, oper...
