  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. 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

  4. 3. Link Adaptation Improvements for Long Term Evolution (LTE)

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Chamila Asanka Ariyaratne; [2009]
    Keywords : LTE; Long Term Evolution; link adaptation; Adaptive modulation and coding;

    Abstract : The Long Term Evolution (LTE) link adaptation is based on measured instantaneous Signal to Interference and Noise Ratio (SINR) which is used for selecting Modulation and Coding Scheme (MCS) for transmissions. In addition, depending on the scheduler, SINR may be used to determine which users are scheduled for a certain transmission time interval and on which frequency resources. READ MORE

  5. 4. Uplink Channel Dependent Scheduling for Future Cellular Systems

    University essay from Institutionen för systemteknik

    Author : Kristina Jersenius; [2007]
    Keywords : channel dependent scheduling; uplink; SC-FDMA; channel quality information; 3GPP Long Term Evolution;

    Abstract : One goal in the development of future cellular systems is to increase performance. Channel dependent scheduling can possibly contribute to a performance enhancement. It requires channel qualityinformation and uplink channel knowledge is often incomplete. READ MORE

  6. 5. Implementation and simulation of HSDPA functionality with ns-2

    University essay from Institutionen för systemteknik

    Author : Haichuan Jianqiu Wu Zhao; [2005]
    Keywords : Reglerteknik; UMTS; HSDPA; ns-2; EURANE; HS-DSCH; DCH; Power Consumption; FCDS; Reglerteknik;

    Abstract : Enhanced packet-data access is a trend in third generation mobile communication system. WCDMA Release 5 introduces HSDPA (High Speed Packet Data Access) with a brand new downlink transport channel HS-DSCH (High Speed Downlink Shared Channel) into 3GPP specification to provide greater capacity.
