Abstract [en]

We derive detection metrics for soft-output diversity combining for  the case of imperfect channel state information at the receiver.  We  treat in particular the case when the noise variance at the receiver  is unknown.  We contrast conventional training-based methods to a  detector based on the generalized likelihood-ratio (GLR) test  paradigm.  We study the performance of the detectors via EXIT chart  analysis and via simulations of LDPC coded transmission over a fast  Rayleigh fading channel.  The results show that the GLR receivers  can significantly outperform the conventional detectors.
