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.

Precoding for coded communication on block fading channels and cooperative communications [PDF]
, 2011 We study precoding for the outage probability minimization of block fading (BF) channels and BF relay channels. Recently, an upper bound on the outage probability with precoding was established for BF channels, but only for high instantaneous SNR.
