2. 11. High speed CMOS optical receiver

   Author : Håkan Bengtson; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Optical communication develops very fast and is today the main method for long distance wired communication. However cost is still high. Looking back to the evolution of optical transmission systems, one main objective of system development has become more and more important; minimize cost per gigabytes per second per kilometre, Gb/s/km.

   Abstract : Digital computers have changed human society in a profound way over the last 50 years. Key properties that contribute to the success of the computer are flexible programmability and fast access to large amounts of data and instructions. READ MORE

5. 13. Channel Shortening in Wireless Communication

   Author : Sha Hu; Kommunikationsteknologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel shortening CS ; multi-input multi-output MIMO ; intersymbol interference ISI ; achievable information rate AIR ; partial marginalization PM ; dirty paper coding DPC ; large intelligent surface LIS ; Cramér-Rao lower bound CRLB ;

   Abstract : The concept of Channel Shortening (CS) is a well-known technique that has a rich history over 40 years. CS transfers linear vector channels such as multi-input multi-output (MIMO) and intersymbol interference (ISI) channels into ``shortened'' versions, for the purpose of reducing demodulation-complexity and improving data-transmission performance.

6. 14. Autoencoders for Physical-Layer Communications: Approaches and Applications

   Author : Jinxiang Song; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; physical-layer communications; neural networks; hardware impairments; machine learning; autoencoders; digital signal processing; equalization.;

   Abstract : The ever-growing demand for higher data rates has driven continuous developments in communication systems over the years. As upcoming high-bandwidth services require even higher data rates, future digital communication infrastructures must undergo continuous upgrades to provide increased capacity. READ MORE

7. 15. Digital block transmission and time-of-flight estimation : receiver design and performance analysis

   Author : Håkan B. Eriksson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Abstract : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. READ MORE
