Timed gradient adaptive lattice equaliser

The paper address the design of timed stochastic gradient-search adaptive lattice filters for applications in channel equalisation. Timing the lattice, i.e. freezing the PARCOR recursion, has previously been shown to offer a significant reduction in the algorithm noise of gradient adaptive lattice filters. Here we further simulate the effects of freezing the recursion, and show the point at which the PARCOR coefficient update process may be stopped and the adaptive combiner operation initiated.
