1. 21. Design and optimization of Bandwidth Part selection for massive beamforming

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Juan Guirado Lopez-Puigcerver; [2020]
   Keywords : Mobile communications; 5G; New Radio NR ; Bandwidth Part BWP ; Beamforming; MU-MIMO; Technology and Engineering;

   Abstract : In the last 30 years, a new mobile communications generation has been developed every 7 to 10 years. The last one that is currently under development is the Fifth Generation. This generation aims to fulfill a wide range of requirements for different use cases. To that end, a new radio access technology called New Radio (NR) has been developed. READ MORE

3. 22. Indoor Positioning Bluetooth Angle of Arrival

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Mohammed M T Amer; Khadeeja Gamal Mohammed Atteya; [2020]
   Keywords : Angle of Arrival; Bluetooth Low energy; Indoor positioning; Internet of Things; Bluetooth direction finding.; Technology and Engineering;

   Abstract : In this thesis, we present the Angle of Arrival (AoA) technique to detect the direction of a source indoors using radio frequency (RF) signal. This technique estimates the direction of the incoming Bluetooth signal, using a tag as a transmitter and an array equipped with a number of antennas as a receiver. READ MORE

4. 23. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Victor Sesma Santos; Victor Egorov; [2020]
   Keywords : Technology and Engineering;

   Abstract : In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. READ MORE

5. 24. Radio signal DOA estimation : Implementing radar signal direction estimation on an FPGA.

   University essay from Linköpings universitet/Datorteknik

   Author : Alfred Patriksson; [2019]
   Keywords : FPGA; DOA; Radar; Direction of Arrival; Monopulse; Amplitude Monopulse; Phase Monopulse;

   Abstract : This master’s thesis covers the design and implementation of a monopulse directionof arrival (DOA) estimation algorithm on an FPGA. The goal is to implement a complete system that is capable of estimating the bearing of an incident signal. READ MORE

6. 25. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Luke Postema; Johan Davidsson; [2019]
   Keywords : Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

   Abstract : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. READ MORE
