Abstract

A radio communications receiver which detects radio signals and recovers data representative of the radio signals in a presence of contemporaneously detected interfering signals, the radio communications receiver having a detector that detects said radio signals and generates digital base band signals representative of the radio signals, a matrix former that forms a correlation matrix having rows and columns from the base band signals, and a data processor that generates a factor matrix of the correlation matrix, the factor matrix having rows and columns, and recovers data from the factor matrix. The data processor generates the factor matrix by calculating first elements of the factor matrix from the correlation matrix using a factorization algorithm in accordance with a pre-determined structure of the factor matrix, and forming second elements of the factor matrix by selectively copying first elements in accordance with the pre-determined structure.
