摘要：

The application of a subspace invariance approach (ESPRIT) to the estimation of parameters (frequencies and powers) of cisoids in noise is described. ESPRIT exploits an underlying rotational invariance of signal subspaces spanned by two temporarilly displaced data sets. The subspace rotation approach has several advantages, including improved resolution, over Pisarenko's technique for harmonic retrieval.
