4. 3. Machine Learning-based MIMO Indoor Positioning

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

   Author : Qiyi Chen; [2023]
   Keywords : Technology and Engineering;

   Abstract : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. READ MORE

5. 4. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

   University essay from Umeå universitet/Institutionen för fysik

   Author : Ossian Kynman; [2023]
   Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

   Abstract : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. READ MORE

6. 5. Beam-steered Modulation in Advanced Antenna System

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