2. 16. Energy-Efficient Data Converters for Low-Power Sensors

   Author : Kairang Chen; Atila Alvandpour; Ana Rusu; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Wireless sensor networks (WSNs) are employed in many applications, such as for monitoring bio-potential signals and environmental information. These applications require high-resolution (> 12-bit) analog-to-digital converters (ADCs) at low-sampling rates (several kS/s). READ MORE

4. 17. Broadband Receiver Electronic Circuits for Fiber-Optical Communication Systems

   Author : Stavros Giannakopoulos; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; broadband amplifiers; data communication; VCSEL; distributed amplifiers.; receiver front-end; short-haul interconnects; InP DHBT; SiGe HBT; TIA;

   Abstract : The exponential growth of internet traffic drives datacenters to constantly improve their capacity. As the copper based network infrastructure is being replaced by fiber-optical interconnects, new industrial standards for higher datarates are required. READ MORE

5. 18. Embedded internet system architectures

   Author : Åke Östmark; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inbyggda system; Embedded System;

   Abstract : Today, using computers is a daily thing for many people over the world. We use computers to for example communicate, read news, search for sport events, correspond with e-mail, participate in meetings, and download the latest polyphonic ring tones for our mobile phones. READ MORE

6. 19. Inverse system identification with applications in predistortion

   Author : Ylva Jung; Martin Enqvist; Lennart Ljung; Torkel Glad; Thomas Eriksson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; inverse models; signal processing; power amplifiers; predistortion; communication electronics;

   Abstract : Models are commonly used to simulate events and processes, and can be constructed from measured data using system identification. The common way is to model the system from input to output, but in this thesis we want to obtain the inverse of the system. READ MORE

7. 20. Optimizing Massive MIMO : Precoder Design and Power Allocation

   Author : Hei Victor Cheng; Erik G. Larsson; Marius Pesavento; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The past decades have seen a rapid growth of mobile data traffic,both in terms of connected devices and data rate. To satisfy the evergrowing data traffic demand in wireless communication systems, thecurrent cellular systems have to be redesigned to increase both spectralefficiency and energy efficiency. READ MORE
