TECHNIQUE FOR GENERATING A FILTER FOR DATA RECEPTION

摘要

A technique for generating a processing filter (F) is provided. The processing filter (F) allows for processing data (140) that is received in a mobile communication network on multiple branches. A method embodiment (400) of the technique includes the steps of determining (410) a covariance (A) of noise on the multiple branches and computing (430) the processing filter (F) based on the noise covariance (A). The computation includes a Cholesky decomposition (440) of the noise covariance (A) and a matrix inversion (450) based on a result of the Cholesky decomposition, wherein the Cholesky decomposition uses a first numerical representation and the matrix inversion uses a second numerical representation that is more complex than the first numerical representation.
