Joint Channel Prediction Aided Differentially Encoded TTCM and BICMID Assisted Eigen-Beamforming
Eigen-beamforming is capable of providing attractive performance gains in the context of multiple-input multiple-output systems, provided accurate channel state information (CSI) is available. However, when a realistic pilot-based channel predictor is used for acquiring the CSI, a significant perfor...

| 520 | |a Eigen-beamforming is capable of providing attractive performance gains in the context of multiple-input multiple-output systems, provided 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 eigenvectors. Sophisticated differentially encoded coded modulation (CM) schemes are amalgamated with the eigen-beamformer, when employing a minimum mean square error based pilot-assisted channel predictor for avoiding the performance degradation imposed by outdated channel estimation. It is shown that the amalgamated differentially encoded CM aided eigen-beamformer attained a coding gain of about 6.5 dB, when communicating over correlated Rayleigh fading channels. | ||
