    Sammanfattning : Cellular networks have significantly transformed the way we communicate and access data and the data rates have only been increasing for the last 30 years. 5G is the current generation of cellular networks and enables faster data rates and lower latency. LÄS MER

  4. 3. Performance Analysis Of Massive MIMO With Port Reduction

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tingrui Zhang; [2022]
    Nyckelord :5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Sammanfattning : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.

  5. 4. RISC-V Based Application-Specific Instruction Set Processor for Packet Processing in Mobile Networks

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Oskar Södergren; [2021]
    Nyckelord :eCPRI; ORAN; ASIP; fronthaul; RISC-V; bit manipulation; 5G; packet processing;

    Sammanfattning : This thesis explores the use of an ASIP for handling O-RAN control data. A model application was constructed, optimized and profiled on a simple RV32-IMC core. The compiled code was analyzed, and the instructions “byte swap”, “pack”, bitwise extract/deposit” and “bit field place” were implemented. LÄS MER

  7. 5. Joint Functional Splitting and Content Placement for Green Hybrid CRAN

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ajay Sriram; [2019]
    Nyckelord :;

    Sammanfattning : A hybrid cloud radio access network (H-CRAN) architecture has been proposed to alleviate the midhaul capacity limitation in C-RAN. In this architecture, functional splitting is utilized to distribute the processing functions between a central cloud and edge clouds. LÄS MER
