2. 1. Channel Estimation and Self-Interference Suppression for MIMO Relaying Systems

   Author : Panagiota Lioliou; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation; expectation-maximization EM ; half-duplex; Bayesian; multiple-input multiple-output MIMO ; Cramer-Rao Bound CRB ; full-duplex; relays; performance analysis; Kalman filter KF ; self-interference.; Amplify-and-forward AF ; least squares LS ;

   Abstract : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.

4. 2. Channel Estimation for Amplify and Forward Relay Networks

   Author : Panagiota Lioliou; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; relay networks; Multiple-input-multiple-output MIMO ; Cramer-Rao Lower Bound CRB .; least squares LS ;

   Abstract : The use of intermediate-relaying nodes has been identified as a promising technique for enhancing coverage and combating the impairments of Multiple-Input-Multiple-Output (MIMO) wireless channels. The main ideais to introduce relays that forward the data to the destination which isotherwise out of the reach of the source. READ MORE
