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

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Nyckelord :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;

    Sammanfattning : 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.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Soumya Jandhyala; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 3. Methods of self-interference cancellation in full duplex telecommunication systems

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Henrik Erlandsson; Viktor Sköldheden; [2021]
    Nyckelord :telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Sammanfattning : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. LÄS MER

  5. 4. Bi-directional Low Pass Filter and Mixer Design

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Sharath Thandava Murthy; Meshach Milon Paul Pear Pradeep Kumar; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This report presents the research and implementation of a bidirectional filter and mixer combination for the transceiver chain in 5G TDD equipment. The main objective of this project is to find a feasible design for mixer and low pass filter to reuse the same hardware blocks for both transmitter and receiver chain. LÄS MER

  7. 5. Investigate Redundancy In Sounding Reference Signal Based Channel Estimates

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik
