ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,388,685, issued on Aug. 12, was assigned to Nokia Solutions and Networks Oy (Espoo, Finland).

"Regularized interference-plus-noise covariance matrix estimation" was invented by Elias Aksel Raninen (Espoo, Finland).

According to the abstract* released by the U.S. Patent & Trademark Office: "Apparatuses and methods in a communication system are disclosed. A signal is received. The signal comprises demodulation reference information. The apparatus compute estimates of the channel and of interference-plus-noise vectors. The interference-plus-noise vectors are used as input for choosing a tapering matrix and for determining shrinkage target matrix and parameter. An interference plus noise...
