  2. 1. Key Signal Processing Technologies for High-speed Passive Optical Networks

    Author : Lei Xue; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural network; passive optical network; optical signal processing; digital signal processing; dispersion supported equalization; Optical access network; semiconductor optical amplifier;

    Abstract : With emerging technologies such as high-definition video, virtual reality, and cloud computing, bandwidth demand in the access networks is ever-increasing. Passive optical network (PON) has become a promising architecture thanks to its low cost and easy management. READ MORE

  4. 2. Identification of dynamic errors-in-variables models

    Author : Kaushik Mahata; Torsten Söderström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Abstract : The problem of identifying dynamic errors-in-variables models is of fundamental interest in many areas like process control, array signal processing, astronomical data reduction. In recent years, this field has received increased attention of the research community. READ MORE

  5. 3. Adaptive blind deconvolution using third-order moments : exploiting asymmetry

    Author : Patrik Pääjärvi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : This thesis focuses on the use of third-order statistics in adaptive blind deconvolution of asymmetric impulsive signals. Traditional methods are typically based on fourthorder moments, which can discriminate signals with heavy-tailed probability functions (i.e. `spiky' signals) from corresponding filtered versions.

  6. 4. High Capacity Fiber-Connected Wireless MIMO Communication

    Author : Husileng Bao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; central unit; Radio-over-Fiber; millimeter-wave.; multiple-inputmultiple- output; remote radio head;

    Abstract : There will be more and more users while beyond-5G (B5G) and 6G bring more wireless applications. Current cellular communication networks assign specific serving boundaries for each radio, which becomes a limitation when too many users work with one radio simultaneously. By physically distributing radios. user’s service can be more uniform. READ MORE

  7. 5. Investigation of Sigma-Delta-over-Fiber for High-Capacity Wireless Communication Systems

    Author : Husileng Bao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; millimeter-wave; multipleinput- multiple-output; remote radio head; Radio-over-fiber; central unit;

    Abstract : The advent of beyond-5G (B5G) and 6G technologies brings increases in wireless devices and their applications. Although massive multiple-input-multiple-output (MIMO) delivers high-capacity services using co-located MIMO (CMIMO) technology, distributed MIMO (D-MIMO) technology offers a more uniform user service.
