Efficient postcoding filter in LU-based beamforming scheme

This paper considers time-domain beamforming in MIMO convolutive systems, using the classical LU-based (Gauss elimination) polynomial matrix decomposition. As the pre- and postfilters are not paraunitary, the output signal-to-noise ratio is degraded compared to QR-based beamforming. We investigate t…
