Online calibration of sensor arrays using higher order statistics
Aktaş, Metin; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2012)
Higher Order Statistics (HOS) and Second Order Statistics (SOS) approaches have certain advantages and disadvantages in signal processing applications. HOS approach provides more statistical information for non-Gaussian signals. On the other hand, SOS approach is more robust to the estimation errors than the HOS approach, especially when the number of observations is small. In this thesis, HOS and SOS approaches are jointly used in order to take advantage of both methods. In this respect, the joint use of H...
Enhanced Modelling of Guitar Distortion
Zeki, Engin; Çiloğlu, Tolga (2015-05-19)
Digital audio effects are used by many electric guitar players. These effects help players to find their desired tones and sounds. For the modelling of main nonlinear guitar effects, distortion and overdrive, this paper investigates current methods of static modelling and dynamic nonlinear state space solutions. After discussion of previous models, this paper introduces a new method of distortion modelling with system identification called Enhanced Modelling of Guitar Distortion. Enhanced Modelling of Guita...
Wavelet domain image resolution enhancement using cycle spinning and edge modelling
Temizel, Alptekin (2005-09-08)
In this paper we present a wavelet domain image resolution en-hancement algorithm. An initial high-resolution approximation to the original image is obtained by means of zero-padding in the wavelet domain. This is further processed using the cycle-spinning methodology which reduces ringing. A critical element of the algo-rithm is the adoption of a simplified edge profile suitable for the description of edge degradations such as blurring due to loss of resolution. Linear regression using a minimal training s...
Panoramic recording and reproduction of multichannel audio using a circular microphone array
Hacıhabiboğlu, Hüseyin (2009-10-18)
Multichannel audio reproduction generally suffers from one or both of the following problems: i) the recorded audio has to be artificially manipulated to provide the necessary spatial cues, which reduces the consistency of the reproduced sound field with the actual one, and ii) reproduction is not panoramic, which degrades realism when the listener is not seated in a desired ideal position facing the center channel. A recording method using a circularly symmetric array of differential microphones, and a rep...
Tracker-aware adaptive detection: An efficient closed-form solution for the Neyman-Pearson case
Aslan, Murat Samil; Saranlı, Afşar; Baykal, Buyurman (Elsevier BV, 2010-09-01)
A promising line of research for radar systems attempts to optimize the detector thresholds so as to maximize the overall performance of a radar detector-tracker pair. In the present work, we attempt to move in a direction to fulfill this promise by considering a particular dynamic optimization scheme which relies on a non-simulation performance prediction (NSPP) methodology for the probabilistic data association filter (PDAF), namely, the modified Riccati equation (MRE). By using a suitable functional appr...
