时差估计算法 Basic aspects of time delay estimation (TDE) based on sampled,signals are investigated in this paper. The direct cross-correlation method is analyzed and compared to the average square difference function (ASDF) and the (addition only based)
Through introducing discrete-time quantum walks on the infinite line and on circles, we present a kind of two-particle interacting quantum walk which has two kinds of interactions. We investigate the characteristics of this kind of quantum walk and t
In this paper, we address the problem of unknown periodicity for a class of discrete-time nonlinear parametric systems without assuming any growth conditions on the nonlinearities. The unknown periodicity hides in the parametric uncertainties, which
