Abstract
A method for determining a precoding matrix for a MIMO transmitter based on a weighted MMSE algorithm is disclosed. A precoding module identically transforms a first matrix expression into a second matrix expression. The first matrix expression comprises a matrix inversion operation of a quadratic matrix having a rank equal to a number of antennas of the MIMO transmitter. The second matrix expression comprises a matrix inversion operation of a quadratic matrix having a rank equal to a number of receivers scheduled for the MIMO transmitter.
