  1. 1. Implementation and Evaluation of Signal Processing Circuits for Optical Communication

    Författare :Erik Börjeson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Equalization; Carrier Phase Recovery; Digital Signal Processing; Application-Specific Integrated Circuits; Communication Systems; Fiber-Optic Communication;

    Sammanfattning : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.

  4. 3. On Linear Transmission Systems

    Författare :Dzevdan Kapetanovic; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO systems; Precoding; Information Theory; Single Carrier Systems; Linear Modulation; Faster-than-Nyquist Signaling.;

    Sammanfattning : This thesis is divided into two parts. Part I analyzes the information rate of single antenna, single carrier linear modulation systems. The information rate of a system is the maximum number of bits that can be transmitted during a channel usage, and is achieved by Gaussian symbols. LÄS MER

  5. 4. Wideband CMOS Data Converters for Linear and Efficient mmWave Transmitters

    Författare :Victor Åberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; Efficient; MIMO; Predistortion; mmWave; RF-DAC; Wideband; SAR ADC; Linear; Linearization;

    Sammanfattning : With continuously increasing demands for wireless connectivity, higher carrier frequencies and wider bandwidths are explored. To overcome a limited transmit power at these higher carrier frequencies, multiple input multiple output (MIMO) systems, with a large number of transmitters and antennas, are used to direct the transmitted power towards the user.

  7. 5. Architecture for programmable network infrastructure

    Författare :Tom Barbette; Laurent Matht; University of Liege; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networking; high-speed; dpdk; netmap; click; fastclick; middleclick; nfv; sdn; dataplane; parallelism; Computer Science; Datalogi;

    Sammanfattning : Software networking promises a more flexible network infrastructure, poised to leverage the computational power available in datacenters. Virtual Net- work Functions (VNF) can now run on commodity hardware in datacenters instead of using specialized equipment disposed along the network path. LÄS MER
