  1. 1. Industrial Scenario using LTE Cellular Network

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Anthony Owondo; Javad Blouchi; [2019]
    Keywords : Technology and Engineering;

    Abstract : This Thesis project used an event-based simulation tool written in MATLAB that modelled a factory scenario. Multiple base stations and a varying number of nodes were modelled. The nodes send data to the base stations and the simulation tool calculates the SINR of the received data and uses this SINR to model a probability of error. READ MORE

  3. 2. Beam-Forming-Aware Link-Adaptation for Differential Beam-Forming in an LTE FDD System

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Mikael Karlsson; [2016]
    Keywords : Beam-Forming-Aware; Link-Adaptation; Differential Beam-Forming; LTE;

    Abstract : The ability for base stations to be able to beam-form their signals, directing the signal energy to specific users, is a topic of research that has been heavily studied during the last decades. The beam-forming technique aims to increase the signal-to-interference-and-noise-ratio of the user and, consequently, increase the capacity and coverage of the communication system. READ MORE

  4. 3. Channel Prediction for Moving Relays

    University essay from Signaler och System

    Author : Ingrid Wiklund; [2013]
    Keywords : Channel prediction;

    Abstract : In mobile communications, channel side information at transmitters can increasecapacity. For moving relays nodes, local nodes placed on buses and trams in urbanareas, the channel state information is outdated for control delays of severalmilliseconds, as in the LTE system. READ MORE

  5. 4. Realistic Multi-Cell Interference Coordination in 4G/LTE

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Sara Örn; [2012]
    Keywords : link adaptation; interference estimation; coordinated scheduling; LTE; 4G; radio resource management;

    Abstract : In the LTE mobile system, all cells use the same set of frequencies. This means that a user could experience interference from other cells. A method that has been studied in order to reduce this interference and thereby increase data rate or system throughput is to coordinate scheduling between cells. READ MORE

  6. 5. Fast Packet Retransmissions in LTE

    University essay from Kommunikationssystem

    Author : Syed Tamoor-ul-Hassan; Serkan Demir; [2011]
    Keywords : Link Adaptation; HARQ; EHF; FTP; VOIP;

    Abstract : The cellular networks are evolving to meet the future requirements of data rate,coverage and capacity. The fourth generation mobile communication system, LTEhas been developed to meet these goals. LTE uses multiple antenna features andlarger bandwidths in order to accomplish this task. READ MORE
