2. 1. The Information-Theoretic Cost of Learning Fading Channels

   Author : Wei Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; finite blocklength; outage capacity; block-fading channel; Shannon capacity; quasi-static fading;

   Abstract : Recent results in communication theory suggest that significant throughput gains in wireless fading networks can be achieved by exploiting network coordination (e.g., CoMP, network MIMO, and interference alignment), provided that each node in the network has perfect channel knowledge.

5. 3. MIMO Transceiver Design for Multi-Antenna Communications over Fading Channels

   Author : Simon Järmyr; Björn Ottersten; Antonio Pascual-Iserte; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In wireless communications, the use of multiple antennas for both transmission and reception is associated with performance gains of fundamental nature. One such gain stems from the spatial-multiplexing capabilities of wireless multiple-input multiple-output (MIMO) channels: Many propagation environments admit several data streams to be conveyed in parallel over a single point-to-point link, setting the stage for significantly increased data rates.

6. 4. Ultra-Reliable Short-Packet Communications: Fundamental Limits and Enabling Technologies

   Author : Johan Östman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultra-reliable low-latency; variablelength stop-feedback; imperfect CSI; channel estimation; HARQ.; joint detection and decoding; short packets; Block-fading channels; multiuser massive MIMO;

   Abstract : The paradigm shift from 4G to 5G communications, anticipated to enable ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of wireless communication systems. Unlike in 4G systems, where the main objective is to provide a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.

7. 5. On MIMO Systems and Adaptive Arrays for Wireless Communication : Analysis and Practical Aspects

   Author : Mattias Wennström; Michael A. Jensen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; antenna array; calibration; MIMO system; flat fading; non-linear amplifier; switched parasitic antenna; analog beamformer; adaptive antenna testbed; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

   Abstract : This thesis is concerned with the use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Both measurement results and theoretical analysis are presented. New transmit strategies are derived and compared to existing transmit strategies, such as beamforming and space-time block coding (STBC). READ MORE
