1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

   Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

3. 2. Simulation and Testing of a MU-MIMO Beamforming System

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

   Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
   Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

   Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

4. 3. Mobile and Mounting Solutions for a Multi-Camera Rig for Live Recordings of Open Heart Surgery

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Oliwer Ekdahl; Hugo Möllerstedt; [2023]
   Keywords : Technology and Engineering;

   Abstract : At the Children’s Heart Center of Skåne University Hospital (BUS) there is an ongoing project with live recordings of open heart surgeries. These recordings will be used for educational purposes, for planning of future surgeries, as well as for evaluating the surgical procedures. READ MORE

5. 4. Evaluating .NET MAUI as a replacement for native Android mobile application development with focus on performance

   University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

   Author : Lukas Palmqvist; [2023]
   Keywords : NET MAUI; cross-platform; Android; performance;

   Abstract : Background: These days when developing applications for mobile platforms, therehave been two main branches to pick between as a developer. The first option– denoted native development – targets only one specific mobile operating system(OS). The other is cross-platform development which can target multiple platformssimultaneously.

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

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

   Author : Smitha Jinnahalli Venugopal; [2023]
   Keywords : 5G-MIMO; Beam-forming; Beam-steering; Advanced antenna systems; Technology and Engineering;

   Abstract : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. READ MORE
