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. Optimization and Fundamental Insights in Full-Duplex Cellular Networks

   Author : Jose Mairton B. da Silva Jr.; Carlo Fischione; Gabor Fodor; Geoffrey Ye Li; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; full-duplex; optimization; power control; assignment; beamforming; millimeter wave; self-interference; multi-antenna; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The next generations of cellular networks are expected to provide explosive data rate transmissions and very low latencies. To meet such demands, one of the promising wireless transmissions candidates is in-band full-duplex communications, which enable wireless devices to simultaneously transmit and receive on the same frequency channel.

   Abstract : In this thesis, aspects of the use of cryogenically cooled rare-earth-ion-doped crystals in the fields of quantum optics and quantum information processing are addressed. The experiments and theoretical considerations referred to in this thesis are based on the coherent transient interaction between light and the ions in the crystals. READ MORE

7. 5. Single frequency broadcasting networks

   Author : Göran Malmgren; KTH; []
   Keywords : ;

   Abstract : An Orthogonal Frequency Division Multiplexing (OFDM) schemeallows all transmitters in a radio network to transmitidentical signals in the same frequency block, forming a socalled Single Frequency Network (SFN). By avoiding frequencyreuse, substantial improvements in bandwidth utilisation arepossible. READ MORE
