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. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Prasetyo Putranto; [2023]
   Keywords : Channel aging; Pilot spacing; Rayleigh; Rician; Spectral efficiency; Uncrewed aerial vehicles; Kanalåldring; Pilotavstånd; Rayleigh; Rician; Spectral effektivitet; Obemannade flygfordon;

   Abstract : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. READ MORE

4. 3. 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

5. 4. Power Estimation Tool for Digital Front-End 5G Radio ASIC

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Rajnandini Bhutada; [2023]
   Keywords : 5G; ASIC; DFE; Carrier Aggregation; Digital Pre-Distortion; Downlink; Uplink; Power Consumption; Power Model; Yield Analysis.;

   Abstract : Application Specific Integrated Circuits (ASICs) are critical to delivering on 5G’s promises of high speed, low latency, and expanded capacity. Digital Front-End (DFE) ASICs are particularly important components because they enhance crucial signal processing activities. READ MORE

6. 5. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator

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

   Author : Oskar Nygren; Axel Sneitz-Björkman; [2022]
   Keywords : Technology and Engineering;

   Abstract : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. READ MORE
