Direction-of-arrival Estimation of Wideband Sources Using Sensor Arrays
To my family. My father and mother. Especially, to my beloved wife Ji-Hyun and my precious Catherine. iii ACKNOWLEDGEMENTS When I came to Georgia Tech, I used to imagine the moment when I graduate and thought that it would take forever to finish my graduate work. Since then, five years passed fast and I have finished my thesis. While I was writing this thesis, I could not help thinking that it ...
متن کاملDifferent Wideband Direction of Arrival(DOA) Estimation methods: An Overview
This paper presents an overview of different types of wideband direction of Arrival (DOA) estimation methods. Direction-finding algorithms have straight forward applications in Sonar and Radar, and are also useful in advanced satellite and cellular communication systems for adaptive beamforming of smart antennas. Coherent Signal Subspace Processing (CSSM), one of the earliest wideband DOA estim...
متن کاملSignal Subspace Transformation for Direction-of-arrival Estimation of Wideband Sources in near Field
A novel adaptive signal subspace transformation for direction-of-arrival (DOA) estimation of wideband sources in the near-field is proposed in this paper. The method is composed of two transformations: signal subspace focusing (SSF) and far-field transformation (FFT). SSF aligns the signal subspaces for different frequencies in the bandwidth of the sources based on focusing matrices. FFT transf...
متن کاملAnalysis of call centre arrival data using singular value decomposition
We consider the general problem of analysing and modelling call centre arrival data. A method is described for analysing such data using singular value decomposition (SVD). We illustrate that the outcome from the SVD can be used for data visualization, detection of anomalies (outliers), and extraction of significant features from noisy data. The SVD can also be employed as a data reduction tool...
