  1. 6. Digital Filter Design Using Semidefinite Programming

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Moa Samuelsson; Jimmy Johansson; Fabian Samuelsson; [2015-02-11]
    Keywords : ;

    Abstract : Abstract This thesis explores an optimization based approach to the design problem of digital filters. We show how a digital filter in the form of a discrete linear time-invariant causal system can be characterized by a non-negative trigonometric polynomial, which in turn can be represented by a positive semidefinite matrix known as Gram matrix representation.

  3. 7. L₁adaptive control of a generic fighter aircraft

    University essay from KTH/Optimeringslära och systemteori

    Author : Andreas Myleus; [2013]
    Keywords : ;

    Abstract : This master's thesis was performed at the section of Flight Control Systems at SAAB Aeronautics in Linköping as a part of my Master of Science in Aerospace Engineering at KTH, Stockholm. This report examines the use of L₁ adaptive control to stabilize the inner longitudinal and lateral loops of a generic fighter aircraft, in the event of failure of the system that measures current speed and altitude.

  4. 8. LIDAR SIGNAL PROCESSING TECHNIQUES : CLUTTER SUPPRESSION, CLUSTERING AND TRACKING

    University essay from KTH/Signalbehandling

    Author : Theodor Sjöstedt; [2011]
    Keywords : ;

    Abstract : Light detection and ranging (Lidar) is an object detection system, which uses the scattering of light, normally in the form of laser, to determine the direction, range, and other properties of a distant target. Due to the short wavelength of the laser beam, compared to traditional radio based ranging systems (radar), atmospheric phenomenon such as precipitation and fog present a major problem due to the water droplets reflectiveness at these wavelengths.

  5. 9. Study and Realisation of Nyquist Rate Filters in Voltage Inverter Switch Technique

    University essay from Institutionen för systemteknik

    Author : Harsha Bharadhwaj; [2006]
    Keywords : Voltage Inverter Switch; VIS; Settling time; Discrete time filters; Bilinear transformation;

    Abstract : Low-sensitivity switched capacitor filters imitating 'R','L' and 'C' can be built by means of capacitances, ordinary switches and voltage inverter switches (VIS). These structures carry the inherent bilinear transformation of their doubly resistively terminated ladder reference filters. READ MORE

  6. 10. Modeling and Prediction of Radio Channels for Orthogonal Frequency Division Multiplexing

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Per-Ola Larsson; [2005]
    Keywords : Technology and Engineering;

    Abstract : In a wireless communication system, the channel is ever changing due to multipath properties such as excess delays and constructive and destructive interference. In a step to optimize system performance, it would be beneficial to have access to channel state information of both present subchannels' future development and subchannels outside the currently used frequency interval.
