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

   Author : Victor Sanchez; [2023]
   Keywords : Deep Reinforcement Learning; Environment-aware navigation; Robotics; Artificial Intelligence; Apprentissage par renforcement profond; Navigation consciente de l’humain; Intelligence Artificielle; Robotique; Djup Förstärkande Inlärning; Människomedveten navigering; Robotik; Artificiell Intelligens;

   Abstract : Reinforcement learning (RL) has seen a fast expansion in recent years of its successful application to a range of decision-making and complex control tasks. Moreover, deep learning offers RL the opportunity to enlarge its spectrum of complex fields. READ MORE

3. 2. Link Adaptation in 5G Networks : Reinforcement Learning Framework based Approach

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

   Author : Siva Satya Sri Ganesh Seeram; [2022]
   Keywords : Link Adaptation; OLLA; AMC; Reinforcement Learning; DDPG; BLER; Länkanpassning; OLLA; AMC; förstärkningsinlärning; DDPG; BLER;

   Abstract : Link Adaptation is a core feature introduced in gNodeB (gNB) for Adaptive Modulation and Coding (AMC) scheme in new generation cellular networks. The main purpose of this is to correct the estimated Signal-to-Interference-plus-Noise ratio (SINR) at gNB and select the appropriate Modulation and Coding Scheme (MCS) so the User Equipment (UE) can decode the data successfully.

4. 3. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

   University essay from KTH/Tillämpad fysik

   Author : Marie Defives; [2022]
   Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

   Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

5. 4. A Graph Attention plus Reinforcement Learning Method for Antenna Tilt Optimization

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

   Author : Tengfei Ma; [2021]
   Keywords : Graph Attention; Reinforcement Learning; Antenna Tilt Optimization; 5G; Attention Mechanism; Graph; DQN; Back- Propagation; Gradient Descent;

   Abstract : Remote Electrical Tilt optimization is an effective method to obtain the optimal Key Performance Indicators (KPIs) by remotely controlling the base station antenna’s vertical tilt. To improve the KPIs aims to improve antennas’ cooperation effect since KPIs measure the quality of cooperation between the antenna to be optimized and its neighbor antennas. READ MORE

6. 5. Hybrid Beamforming Design for Full-Duplex mmWave Relaying Systems

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

   Author : Zhe Wu; [2020]
   Keywords : mmWave; full-duplex; hybrid beamforming; self-interference cancellation; OMP; fast ADMM; convergence; mmwave; fullständig duplex; hybridstrålformning; självförstörande annullering; OMP; snabb ADMM; konvergens;

   Abstract : With the tremendous growth in the mobile data traffic, the demand for highdata rate is increasing rapidly, and higher frequency resources shall be exploredto alleviate the congestion in the overcrowded spectrum, thus, the millimeterwave (mmWave) frequency resource ranging from 30 GHz to 300 GHz has beenrecognized as a nature fit for the fifth-generation (5G) and beyond network. Tocompensate the severe path-loss in the mmWave band as well to realize theefficient transmissions by applying the low-cost architecture, it is of intereststo investigate the beamforming schemes with large-scale antenna arrays andthe full-duplex (FD) relaying strategy, which are indispensable in the operationof directional signal transmission and the efficient spectrum utilization inthe mmWave transmission, respectively.
