Comparison of precoding methods for broadband MIMO systems [PDF]
, 2009 In this paper we investigate non-linear precoding solutions for the problem of broadband multiple-input multipleoutput (MIMO) systems. Based on a broadband singular value decomposition (BSVD) we can decouple a broadband MIMO channel into independent ...

Constellation Precoded Beamforming [PDF]
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009 We present and analyze the performance of constellation precoded beamforming. This multi-input multi-output transmission technique is based on the singular value decomposition of a channel matrix. In this work, the beamformer is precoded to improve its diversity performance.
