  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. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysik

    Författare :Alexander Bengtsson; [2017]
    Nyckelord :Optical Fibers; Fiber Noise Cancellation; Laser Stabilization; Slow Light Laser Locking; Technology and Engineering;

    Sammanfattning : An electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. LÄS MER

  4. 3. Optical Fiber Phase Noise Cancellation for Slow Light Crystal Cavity Locking

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Mohammad Tasnimul Haque; [2016]
    Nyckelord :Optical Fiber; Phase Noise; Slow Light; Stabilisation; Quantum Information; Quantum Optics; Optical Clocks; Physics and Astronomy;

    Sammanfattning : Recent developments in the field of optical clocks and quantum information have fueled the necessity for both fiber phase noise cancellation and laser stabilisation. The Quantum Information group at Lund University is conducting research on quantum computation experiments based on rare earth ion doped crystals and also application of slow light effects induced by spectral hole burning in these rare earth ion doped crystals.

  5. 4. Fiber noise cancellation

    Master-uppsats, Lunds universitet/Atomfysik

    Författare :Anders Rönnholm; [2012]
    Nyckelord :Fiber noise; Optical fiber; Laser; Narrow linewidth laser; Physics and Astronomy;

    Sammanfattning : Optical fibers induces phase noise when used to transmit a laser beam due to its small variations in optical length caused by temperature- or pressure changes, or vibrations. This induced phase noise, called fiber noise, is often neglectable, but when used to transmit laser beams with extremely narrow linewidth this fiber noise is of great importance. LÄS MER
