  1. 1. PLL for 5G mmWave

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

    Author : Daniel Bakic; Jinzhuo Wu; [2020]
    Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

  3. 2. Task scheduling for dual-arm industrial robots through Constraint Programming

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Tommy Kvant; [2015]
    Keywords : Constraint Programming; MiniZinc; JaCoP; G12; Gecode; or-tools; Opturion CPX; Choco3; scheduling; dual-arm robots; Technology and Engineering;

    Abstract : In a society where more and more production becomes automated it demands robots that are as flexible and versatile as humans. Such flexibility demands automatic scheduling of tasks. READ MORE

  4. 3. Speech enhancement methods in hands-free communication with emphasis on Optimal SNIR Beamformer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Harish Midathala; [2012]
    Keywords : signal to noise ratio; Beamforming; Reverberated and Anechoic; Speech intelligibility; Reverberation.;

    Abstract : A basic speech enhancement can be achieved by the suppression of background noise and reverberation from the clean speech. The point to be noted is to achieve it with a low computational complexity. The aim is to estimate signal arriving optimally from the desired direction in the presence of reverberant-noisy speech signal. READ MORE

  5. 4. Keystroke Resilience in Laptop Acoustics Using Wiener Beamformer and Spectral Subtraction

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abhiram Chintakuntla; [2012]
    Keywords : Wiener Beamformer; Spectral Subtraction; Filter Banks; FD Filters.;

    Abstract : Nowadays, Laptops and Personal computers are increasingly being used to capture audio in various communication scenarios such as video conferencing, recordings of meetings, VOIP communications and lectures for archival purposes and audio/video instant messaging. Many of these scenarios often face unique problem of additive noise that of the user simultaneously typing on the keyboard. READ MORE
