  1. 11. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO

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

    Författare :Francisco Goncalves Contente; [2020]
    Nyckelord :;

    Sammanfattning : Hybrid Beamforming in multiple input multiple output systems has surged in the past few years as the prime precoding architecture for massive MIMO systems since it addresses the systems performance and complexity/power consumption tradeoff. Most of the literature addresses HBF MIMO with a fixed antenna subarray, however it is possible to further increase the spectral efficiency of the system by dynamically configuring the HBF MIMO subarray according the channel state information of the users.

    Nyckelord :MIMO; SVM; Machine Learning; Power DelayProfile; Spatial Correlation; Wireless Radio Channel;

    Sammanfattning : Nowadays, identification of fake data is an elaboratechallenge that calls for the use of machine learning techniques.This is due to the huge amount of data and its complexity makesthe differences indistinguishable even for the trained eye. LÄS MER

  5. 14. Nonlinear effects and predictions in advanced antenna systems in 5G Distortion Effects in 5G

    Master-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Altahra Mohammed; [2019]
    Nyckelord :PA; DPD; Active load-pull; Calibration.;

    Sammanfattning : In the next-generation wireless cellular communication systems known as 5G, radio equipment will be deployed in several frequency bands, among them is the millimeter wave bands (26 - 40 GHz). The use of these high frequencies can help to mitigate the limited spectrum problem and higher data rates can be achieved [2] . LÄS MER
