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
