1. 1. Personalized Federated Learning for mmWave Beam Prediction Using Non-IID Sub-6 GHz Channels

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yuan Cheng; [2022]
   Keywords : Personalized Federated Learning; Millimeter wave; Beamforming; DeepMIMO; Non-IID; Personaliserad Federad Inlärning; Millimetervågor; Strålformning; DeepMIMO; Icke-IID;

   Abstract : While it is difficult for base stations to estimate the millimeter wave (mmWave) channels and find the optimal mmWave beam for user equipments (UEs) quickly, the sub-6 GHz channels which are usually easier to obtain and more robust to blockages could be used to reduce the time before initial access and enhance the reliability of mmWave communication. Considering that the channel information is collected by a massive number of radio base stations and would be sensitive to privacy and security, Federated Learning (FL) is a match for this use case.

3. 2. Presence detection by means of RF waveform classification

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Max Lengdell; [2022]
   Keywords : presence detection; machine learning; radio wave classification; unsupervised learning; supervised learning; sensor fusion; unsupervised classification;

   Abstract : This master thesis investigates the possibility to automatically label and classify radio waves for presence detection, where the objective is to obtain information about the number of people in a room based on channel estimates. Labeling data for machine learning is time consuming and tedious process. To address this two approaches are evaluated. READ MORE
