1. 1. Evaluating user preference when applying mipmap LOD in shadow covered textures

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Jonas Berggren; [2020]
   Keywords : Textures; Mipmapping; Shadow Mapping; Level of Detail;

   Abstract : Background. Shadow mapping is a method that is used for generating and imitating shadows in 3D-spaces. This technique has been used in the entertainment media industry in the form of games, movies and 3D renderings of environments to create a more realistic experience for consumers. READ MORE

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

   Author : Axel Berg; [2017]
   Keywords : IoT NB-IoT OTDOA Positioning; Technology and Engineering;

   Abstract : This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. READ MORE

4. 3. Cell Acquisition and Synchronization for Unlicensed NB-IoT

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Eskil Jörgensen; [2017]
   Keywords : Narrowband Internet-of-Things; NB-IoT; unlicensed; cell search; cell acquisition; synchronization; artificial fast fading; binary sequences; peak sidelobe level;

   Abstract : Narrowband Internet-of-Things (NB-IoT) is a new wireless technology designed to support cellular networks with wide coverage for a massive number of very cheap low power user devices. Studies have been initiated for deployment of NB-IoT in unlicensed frequency bands, some of which demand the use of a frequency-hopping scheme with a short channel dwell time. READ MORE
