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:
r1(t) = s(t) + n1(t)
R2(t) = s(t - D(t)) +n2(t)
Where s [Formula Omitted] is Signal and n1 (•) and n2 (•) Are Noise. Simulation Results Are Presented and Discussed. Copyright © 1987 by the Institute of Electrical and Electronics Engineers, Inc.
