摘要：

By incorporating prior knowledge of known signal poles corresponding to some of the closely spaced sinusoids, Dowling et al. have proposed an LCTLS-FLP technique. which improves the performance of TLS-FLP. Here, we present two better estimators that incorporate the same prior know-ledge hut clearly outperform LCTLS-FLP in resolution and parameter accuracy.
