Signal estimation via Laguerre series

This paper demonstrates that Laguerre series can be used to estimate a variety of signals, including (a) transient signals; (b) infinitely persisting finite power signals; and (c) signals that explode. One of the examples presented is the estimation of the step response of a linear time invariant system which leads to a discussion of the relationship of the proposed technique with the classical system identification algorithm due to B. L. Ho.
