1. Digital Front End Algorithms for Sub-Band Full Duplex
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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.

2. Joint CFR and DPD optimization for 5G Digital Front Ends
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : 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.

3. Power Estimation Tool for Digital Front-End 5G Radio ASIC
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskapSammanfattning : 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. LÄS MER
4. Algorithmic Multi-Ported Memories Enabled Power-Efficient Pre-Distorter Design in ASIC
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The transition from the 5G to the 6G era is a pivotal juncture in contemporary wireless communication. Under such a circumstance, Digital Pre-Distortion (DPD) technology has established its significance as an effective method to linearize Power Amplifiers. LÄS MER
5. Self-organizing Maps for Digital Pre-distortion
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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. LÄS MER
