  1. 1. Blind Channel Equalization for Shortwave Digital Radio Communications

    University essay from Linköpings universitet/Reglerteknik

    Author : Tomas Busk; [2020]
    Keywords : Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Abstract : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  3. 2. GPS-oscillation-robust Localization and Visionaided Odometry Estimation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : HONGYI CHEN; [2019]
    Keywords : Adaptive Extended Kalman Filter; Localization; Stereo visual odometry; GPS outage; Adaptivt förlängt Kalmanfilter; lokalisering; stereovisuell odometri; GPS avbrott;

    Abstract : GPS/IMU integrated systems are commonly used for vehicle navigation. The algorithm for this coupled system is normally based on Kalman filter. However, oscillated GPS measurements in the urban environment can lead to localization divergence easily. READ MORE

  4. 3. Stabilization of Manually Controlled Sight-Systems for Tracking Tasks

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

    Author : Steffany Reyna Marquez; [2019]
    Keywords : ;

    Abstract : In this thesis, we analyze the influence of an operator during manual control tasks in order toimprove her tracking ability. The operator sends control commands to a sight system so that shecan, among other things, track a target. READ MORE

  5. 4. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation & Choosing DPSS Parameters

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Carl-Henrik Hanquist; [2018]
    Keywords : DPSS; Multitaper; Radar;

    Abstract : One of the biggest challenges in any airborne radar is to distinguish a target from a strong ground echo. The main problem is that the ground echo, called ground clutter, can be up to a million times stronger than the response from the target in question. READ MORE

  6. 5. Acoustic feedback suppression in audio mixer for PA applications

    University essay from Umeå universitet/Institutionen för fysik

    Author : Mattias Ekström; [2017]
    Keywords : Digital signal processing; feedback suppression;

    Abstract : When a speaker is addressing an audience, a PA system consisting of a microphone and a loudspeaker is often used. If the microphone picks up too much of the loudspeaker energy, acoustic feedback in the form of an unwanted characteristic howling can occur. READ MORE
