  2. 1. 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

  4. 2. Reconfigurable Analog to Digital Converters for Low Power Wireless Applications

    Author : E. Martin I. Gustafsson; Ana Rusu; Georges Gielen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Circuits; Analog to Digital Converters; Wireless communication; Electronics Engineering; Electrical Engineering; Electronics; Elektronik;

    Abstract : The commercialization of Marconi’s radio transmission and reception, along with the development of integrated circuits in the 1960’s have facilitated many new consumer products for wireless communication, where the mobile phones or handsets are one. These handsets started out as a portable phone, mounted in cars, and have with time added additional services as Short Message Service, and have today become a media center with global positioning, and high-speed internet connection.

  5. 3. Early-Decision Decoding of LDPC Codes

    Author : Anton Blad; Oscar Gustafsson; Erik G. Larsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECC; LDPC; communication; coding; decoding; low-power; Tanner; iterative algorithms; Electronics; Elektronik;

    Abstract : Since their rediscovery in 1995, low-density parity-check (LDPC) codes have received wide-spread attention as practical capacity-approaching code candidates. It has been shown that the class of codes can perform arbitrarily close to the channel capacity, and LDPC codes are also used or suggested for a number of important current and future communication standards.

    Abstract : Soft matter, here, liquids and polymers, have adaptability to a surrounding geometry. They intrinsically have advantageous characteristics from a mechanical perspective, such as flowing and wetting on surrounding surfaces, giving compliant, conformal and deformable behavior.
