  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

    Master-uppsats, KTH/Matematisk statistik

    Författare :Danilo Peng; [2019]
    Nyckelord :Machine learning; 5G; interference channel; blind source estimation; MIMO; OFDM; bandwidth prediction; support vector machines; artificial neural network.; Maskininlärning; 5G; interferencekanal; stödvektormaskin; neurala nätverk; brandbedd estimering;

    Sammanfattning : The data traffic has been growing drastic over the past few years due to digitization and new technologies that are introduced to the market, such as autonomous cars. In order to meet this demand, the MIMO-OFDM system is used in the fifth generation wireless network, 5G. LÄS MER

  5. 4. Deep Learning for Error Prediction In MIMO-OFDM system With Maximum Likelihood Detector

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

    Författare :Baoqing She; [2018]
    Nyckelord :MIMO-OFDM; CRC; BLER; Detector; SINR; MCS Selection; Link Adaptation; Deep Learning; Neural Networks;

    Sammanfattning : To increase link throughput in multi-input multi-output (MIMO) orthogonal frequencydivision multiplexing (OFDM) systems, transmission parameters such as code rate andmodulation order are required to be set adaptively. Therefore, block error rate (BLER)becomes a crucial measure which illustrates the quality of the link, thus being used in LinkAdaptation (LA) to determine the transmission parameters. LÄS MER

  7. 5. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Mahesh Aleti; Rahamatulla Syed; Rajendra Prasad Chennupati; [2014]
    Nyckelord :Cognitive Radio; Power Control; the Fuzzy Interference System FIS ; ANFIS; “MIMO” “Multiple Input Multiple Output” ; “OFDM” “Orthogonal Frequency Division Multiplexing” ; AWGN; BER; SNR; Eb N0;

    Sammanfattning : Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. LÄS MER
