TECHNIQUE FOR GENERATING A FILTER FOR DATA RECEPTION

摘要

A technique for generating a processing filter is provided. The processing filter allows for processing data that is received in a mobile communication network on multiple branches. A method embodiment of the technique includes the steps of determining a covariance of noise on the multiple branches and computing the processing filter based on the noise covariance. The computation includes a Cholesky decomposition of the noise covariance and a matrix inversion 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.
