  1. 11. Fundamental Performance Limits on Time of Arrival Estimation Accuracy with 5G Radio Access

    University essay from KTH/Teknisk informationsvetenskap

    Author : Dehan Luan; [2017]
    Keywords : ;

    Abstract : 5G radio access technology stimulates new use cases and emerging businessmodels, evolving the world to become a fully mobile and connected networksociety, expected to be operational by 2020. To enable ultra-high reliable andhighly precise features, there are more stringent positioning accuracy requirementsfor location based services and E911 emergency calls, targeting at bothindoor and outdoor users which include humans, devices, vehicles and machines.

  3. 12. Train Localization and Speed Estimation Using On-Board Inertial and Magnetic Sensors

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Erik Hedberg; Mikael Hammar; [2015]
    Keywords : signal processing; railway tracks; trains; localization; speed estimation;

    Abstract : Positioning systems for trains are traditionally based on track-side infrastructure, implying costs for both installation and maintenance. A reliable on-board system would therefore be attractive. Sufficient reliability for on-board systems is likely going to require a multi-sensor solution. READ MORE

  4. 13. Multi-Pitch Estimation of Inharmonic Signals

    University essay from Lunds universitet/Matematisk statistik

    Author : Tommy Nilsson; [2013]
    Keywords : Mathematics and Statistics;

    Abstract : A signal with harmonic structure is often characterized by its fundamental frequency, or pitch. This single parameter contain vital information of a range of applications such as musical transcription, tuning of stringed instruments, speech processing and more. READ MORE

  5. 14. Real-time monitoring of voice characteristics usingaccelerometer and microphone measurements

    University essay from Reglerteknik

    Author : Marcus Virebrand; [2011]
    Keywords : Pitch detection; Phonation time; Sound pressure level;

    Abstract : VoxLog is a portable voice accumulator, that uses both an accelerometer that measures skin vibrations and a regular microphone to collect data. The goal of the thesis was to implement and evaluate methods that based on this data estimate the three different voice parameters fundamental frequency, phonation and soundpressure level. READ MORE

  6. 15. Design of Harmonic Filters for Renewable Energy Applications

    University essay from Institutionen för kultur, energi och miljö

    Author : Bhunesh Kumar; [2011]
    Keywords : Digital Filter; Impulse Response; Wave Digital Filter; Circulator-Tree WAVE Digital Filter; Harmonics Filter; Renewable energy Filter; Wind Energy Filter; Butterworth; Chebyshev and Cauer filters; Low-pass; High-pass and Band-pass filters;

    Abstract : Harmonics are created by non-linear devices connected to the power system. Power system harmonics are multiples of the fundamental power system frequency and these harmonic frequencies can create distorted voltages and currents. Distortion of voltages and currents can affect the power system adversely causing power quality problems. READ MORE
