The influence of different PAST-based subspace trackers on DaPT parameter estimation

[摘要] In the context of parameter estimation, subspace-based methods like ESPRIThave become common. They require a subspace separation e.g. based oneigenvalue/-vector decomposition. In time-varying environments, this can bedone by subspace trackers. One class of these is based on the PAST algorithm.Our non-linear parameter estimation algorithm DaPT builds on-top of theESPRIT algorithm. Evaluation of the different variants of the PAST algorithmshows which variant of the PAST algorithm is worthwhile in the context offrequency estimation.
