Abstract

Signal registration is concerned with the problem of estimating a varying displacement between two random processes. We approach signal registration here as a recursive demodulation problem in which the recursion is between signal estimations and displacement estimation. Special attention is given to the problem of estimating a variable time delay. Thus, we present new algorithms for estimating D(t) from received processes: [eq.] where s [formula omitted] is signal and n1 (•) and n2 (•) are noise. Simulation results are presented and discussed.
