Generalized Time-Updating Sparse Covariance-Based Spectral Estimation

Generalized Time-Updating Sparse Covariance-Based Spectral Estimation

Recently, the time-updating q -norm sparse covariance-based estimator (q -SPICE) was developed for online spectral estimation of stationary signals. In this work, this development is furthered to deal with non-stationary signals. By introducing a weighting matrix defined by a forgetting factor, the...
