  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. Full Duplex for Joint Communication and Sensing in 6G.

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Soumya Jandhyala; [2023]
    Keywords : ;

    Abstract : Background: 6G mobile communication is one of the fastest-growing fields of technology. The present 5G mobile networks will not be adequate to meet society’s wireless connectivity demand in the near to mid-term future. A new generation of wireless mobile networks has to be developed to address this demand. READ MORE

  4. 3. Fault detection and diagnosis through tool based expert rule methodology

    University essay from KTH/Hållbara byggnader

    Author : RODRIGO ESTUARDO PÉREZ ARBIZÚ; [2023]
    Keywords : ;

    Abstract : This thesis aims to develop a set of expert rules for fault detection and diagnosis,specifically for the Korsningen HVAC system, which has different sections, includingheat pumps, ventilation, supply/return hot and cold, chill beams, and radiators.The analysis focuses on identifying the most important sensors and other componentsthat provide valuable information to compress the data and improve systemreliability, reduce downtime, and increase efficiency.
