  1. 1. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zhenyu Li; [2023]
    Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

  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. A Digital Phase-Locked Loop for Frequency Synthesis using an Adaptive Pulse Shrinking TDC

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

    Author : Viktor Lewin; [2023]
    Keywords : Phase-locked loop; PLL; DPLL; Frequency Synthesis; TDC; PFD; Technology and Engineering;

    Abstract : This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. READ MORE

  5. 4. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Richter; [2023]
    Keywords : Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

    Abstract : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

  6. 5. Exploring Near-Field SAR with mmWave Pulsed Coherent Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Elina Yrlid; [2023]
    Keywords : SAR; Synthetic Aperture Radar; PCR; pulsed coherent radar; radar; mmWave; millimeter-wave; near-field; 60GHz; Technology and Engineering;

    Abstract : This thesis explores the option to apply Synthetic Aperture Radar (SAR) techniques to image near-field targets utilizing mmWave pulsed coherent radar (PCR). The recent development of mmWave radars has broadened the scope for SAR, but there are few concrete examples explaining and demonstrating the fundamental SAR algorithms from a PCR perspective.
