  1. 1. High Capacity Fiber-Connected Wireless MIMO Communication

    Författare :Husileng Bao; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Phase Noise in Communication Systems--Modeling, Compensation, and Performance Analysis

    Sammanfattning : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. LÄS MER

  5. 4. Fairness in Communication and Computer Network Design

    Författare :Pål Nilsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data- och systemvetenskap; computer technology; Systems engineering; Resource allocation; Optimization; Communication networks; Fairness; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : In communication networks, fair sharing of resources is an important issue for one main reason. The growth of network capacity is in general not matching the rapid growth of traffic. Consequently, the resources consumed by each user have to be limited. This implies that users cannot always be assigned the end-to-end bandwidth they ask for. LÄS MER

  7. 5. Wideband integrated circuits for optical communication systems

    Författare :Stavros Giannakopoulos; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical interconnects; SiGe HBT; receiverfront-end; VCSEL driver; wideband amplifiers; data communication; InP DHBT; TIA; distributed amplifiers.;

    Sammanfattning : The exponential growth of internet traffic drives datacenters to constantly improvetheir capacity. Several research and industrial organizations are aiming towardsTbps Ethernet and beyond, which brings new challenges to the field of high-speedbroadband electronic circuit design. LÄS MER
