  1. 1. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

    M1-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Författare :Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
    Nyckelord :5G NR; Channel Estimation; MIMO; OFDM; DMRS;

    Sammanfattning : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. LÄS MER

    Sammanfattning : The demand of different multimedia services and different internet supported applications on mobile devices requires a high speed data rate and good service of quality. This can be obtained by implementing multiple Antenna technology on both stations i.e. LÄS MER

  4. 3. A study of closed loop space time block coding techniques for MIMO-OFDM

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :Shabbar Ali Khan; [2006]
    Nyckelord :closed loop space time block coding;

    Sammanfattning : In this dissertation, the STBC-OFDM technique is therefore investigated in order to improve the bit error rate performance of such wireless communication systems speci¯cally those using multiple transmitter and receiver antennas.An investigation is undertaken of STBC with two transmit and one receive antennas as proposed by Alamouti together with quasi-orthogonal STBC with four transmit and one receive antennas.
