2. 1. Exploring Alternative Massive MIMO Designs : Superimposed Pilots and Mixed-ADCs

   Author : Daniel Verenzuela; Emil Björnson; Luca Sanguinetti; Michalis Matthaiou; Mohamad Assaad; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The development of information and communication technologies (ICT) provides the means for reaching global connectivity that can help humanity progress and prosper. This comes with high demands on data traffic and number of connected devices which are rapidly growing and need to be met by technological development. READ MORE

5. 3. Channel Estimation in Wireless Communication Systems Employing Multiple Antennas

   Author : Mikael Coldrey; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; capacity; channel estimation; non-parametric estimation; training; distributed sources; MIMO; Wireless communications; superimposed pilots; performance bounds;

   Abstract : Antennas that are able to adaptively direct the transmitted (and received) energy are of great interest in future wireless communication systems. The directivity implies reduced transmit power and interference, and also a potential for increased capacity. READ MORE

6. 4. Influence of Channel Estimation on Wireless Communication System Performance

   Author : Patrik Bohlin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Many wireless communication systems today employ receivers that use channel estimation as an integral part of the receiver chain. Two sides of this problem are studied in this thesis: Impact of channel estimation on low complexity receivers for multi antenna and CDMA systems, and the performance of systems based on superimposed pilots and systems with peak power constraints.
