  2. 21. High speed communication on twisted-pair wires and low complexity multiuser detectors

    Author : Frank Sjöberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis deals with two different topics: High speed communication on twisted pair wires (digital subscriber lines) and low complexity multiuser detectors. The major part of this thesis concerns a technique for high speed communication over the telephone network called Very high bit rate Digital Subscriber Line VDSL). READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time delay estimation; OFDM; carrier frequency offset; Signal processing; Signalbehandling;

    Abstract : The demand for reliable high rate and efficient communication is ever increasing. In this thesis we look at two different problems in such systems, and their possible solutions. READ MORE

  5. 23. Pattern-based Programming Abstractions for Heterogeneous Parallel Computing

    Author : August Ernstsson; Christoph Kessler; José Daniel García Sánchez; Herbert Kuchen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High‐level parallel programming; Algorithmic skeletons; Heterogeneous systems; High‐performance computing;

    Abstract : Contemporary computer architectures utilize wide multi-core processors, accelerators such as GPUs, and clustering of individual computers into complex large-scale systems. These hardware trends are prevalent across computers of all sizes, from the largest supercomputers down to the smallest mobile phones. READ MORE

  6. 24. Efficient Processing and Storage for Massive MIMO Digital Baseband

    Author : Yangxurui Liu; Integrerade elektroniksystem; []
    Keywords : digital signal processor; baseband processing; parallel memories; data compression; channel sparsity; Reconfigurable computing; QR decomposition; resource scheduling; massive MIMO; MIMO; DVFS;

    Abstract : Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its actual deployment.
