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. Joint CFR and DPD optimization for 5G Digital Front Ends

   University essay from Lunds universitet/Matematik LTH

   Author : Gustav Olsson; [2023]
   Keywords : Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

   Abstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

6. 5. Self-organizing Maps for Digital Pre-distortion

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

   Author : Michail Isaakidis; [2020]
   Keywords : Self-organizing maps; Digital pre-distortion; Technology and Engineering;

   Abstract : Power amplifiers are very important components in the area of wireless communications. However, they are non-linear devices and they seem to achieve high efficiency when they are operating in the non-linear regions, at the cost of being more power-consuming. In order to linearize their behavior, designers have been considering many methods. READ MORE
