Channel Prediction Aided Coded Modulation Assisted Eigen-Beamforming

Ng, S.X., Liu, W., Yang, L-L. and Hanzo, L. (2007) Channel Prediction Aided Coded Modulation Assisted Eigen-Beamforming At IEEE VTC'07 (Spring). 22 - 25 Apr 2007. , pp. 1742-1746.

Record type: Conference or Workshop Item (Paper)


Eigen-beamforming is capable of providing attractive performance gains in the context of Multiple-Input Multiple-Output (MIMO) systems, provided that accurate Channel State Information (CSI) is available. However, when a realistic pilot-based channel predictor is used for acquiring the CSI, a significant performance degradation may be imposed by the phase-ambiguity inherent in the estimated eigen-vectors. In this contribution, both sophisticated Coded Modulation (CM) schemes and differentially encoded CM schemes are employed for assisting the operation of the eigen-beamformer, when employing a minimum mean square error based pilot-assisted channel predictor. It is shown that differentially encoded CM schemes are capable of assisting the eigen-beamformer in attaining a coding gain of about 6.5 dBs, when communicating over correlated Rayleigh fading channels.
