Abstract

An autoregressive parameter estimation algorithm combined with a generalized expectation- minimization approach is used to provide a recursive procedure for spectral analysis of real data corrupted by sparkling interferences. The prediction filter is stable and estimated with low bias. These properties also guarantee fast convergence. Results of the real data processing are represented.
