Efficient filter weight computation for a MIMO system using eigenvalue decomposition

摘要

A technique to efficiently derive a spatial filter matrix is described. A first matrix is formed based on the channel response matrix (312) and decomposed to obtain a unitary matrix and a diagonal matrix (314). The spatial filter matrix is derived based on the unitary matrix, the diagonal matrix, and the channel response matrix (316). The eigenvalue decomposition may be obtained by performing a plurality of Jacobi rotations on the first matrix.
