  2. 1. Estimation and detection of transmission line characteristics in the copper access network

    Author : Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital subscriber line; DSL; line qualification; twisted-pair line; copper access network; cable modeling; crosstalk channel estimation; estimation; detection;

    Abstract : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. READ MORE

  4. 2. Peak and Power Reduction in Multicarrier Communication Systems

    Author : Niklas Andgart; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; line driver; Signal processing; Signalbehandling; Telecommunication engineering; power reduction; DSL; DMT; tone reservation; PAR; Peak to average ratio;

    Abstract : Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. READ MORE

  5. 3. Common-Mode Aided Wireline Communications

    Author : Thomas Magesacher; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; DSL; multicarrier modulation; DMT; Shannon capacity; channel modelling; common mode; wireline communications; information processing;

    Abstract : Wireline communication is the Internet access technology with the largest number of subscribers worldwide. On physical-layer level, the traditional way to transmit signals at one end of a wire pair and to extract receive signals at the other end is to apply differential-mode signalling: transmit and receive signals correspond to voltage differences between the two wires.

  6. 4. Obsidian: GPU Kernel Programming in Haskell

    Author : Joel Bo Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Haskell; data-parallelism; GPGPU; DSL; CUDA; parallelism; Obsidian; GPU; NVIDIA; Language design; ; EDSL;

    Abstract : Graphics Processing Units (GPUs) are evolving into powerful general purpose computing platforms. At first, GPU performance was driven by the requirements of 3D graphics computer games. To fit this workload, a GPU is a many-core processor suitable for the data-parallel programming paradigm. READ MORE

  7. 5. Older Adults with Dual Sensory Loss : Prevalence, Diagnoses & Rehabilitation Services

    Author : Elin Lundin; Stephen Widén; Agneta Anderzén-Carlsson; Moa Wahlqvist; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dual sensory loss; Healthy aging; Older adults; Prevalence; Rehabilitation services; Qualitative content analysis; Funktionsnedsättning och samhälle; Disability research;

    Abstract : Introduction: Globally, the population aged 65 years and older are predicted to double within 30 years. The risk of developing vision loss in combination with hearing loss – dual sensory loss (DSL) increases with age. READ MORE
