2. 1. High Efficiency Light Field Image Compression : Hierarchical Bit Allocation and Shearlet-based View Interpolation

   Author : Waqas Ahmad; Mårten Sjöström; Roger Olsson; Peter Schelkens; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Over the years, the pursuit of capturing the precise visual information of a scenehas resulted in various enhancements in digital camera technology, such as highdynamic range, extended depth of field, and high resolution. However, traditionaldigital cameras only capture the spatial information of the scene and cannot pro-vide an immersive presentation of it. READ MORE

4. 2. Low Cost Remote Antenna Units in CMOS for Fiber-fed Distributed MIMO Systems

   Author : Waqas Ahmad; Institutionen för elektro- och informationsteknik; []

   Abstract : Massive multiple input multiple output (MIMO) is a revolutionary communication technique, where large numbers of antennas are employed at the base stations to increase the spectral efficiency, reliability and data rate of the system. Moreover, in multi-user MIMO (MU-MIMO) multiple users can be served by the base stations on the same time-frequency resource. READ MORE
