New approaches for channel estimation in wireless communications
(Işık Üniversitesi, 2006-03-10)
This thesis first proposes a conputationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorthm for the orthogonal frequency division multiplexing OFDM systems in unkonown ...
Circuit models with mixed lumped and distributed elements for passive one-port devices
(Işık Üniversitesi, 2006-01-23)
In this thesis, to model measured data obtained from an actual passive one-port device, a circuit modeling method with mixed lumped and distributed elements is proposed. Namely, measured data is modelled by means of its ...
Solid-state arrays and beamformers for side-looking intravascular ultrasonic imaging
(Işık Üniversitesi, 2010-06-08)
Current solid-state intravascular ultrasound (IVUS) devices use a one-dimensional (1-D) rectangular array wrapped around the cylindrical catheter. Beamforming in these devices is limited to synthetic phased array processing, ...
Co-training using prosodic, lexical and morphological information for automatic sentence segmentation of Turkish spoken language
(Işık Üniversitesi, 2018-01-15)
Sentence segmentation of speech aims detecting sentence boundaries in a stream of words output by the speech recognizer. Sentence segmentation is a preliminary step toward speech understanding. It is of particular importance ...
Facial expression recognition based on facial anatomy
(Işık Üniversitesi, 2013-06-06)
In this thesis we propose to determine the underlying muscle forces that compose a facial expression under the constraint of facial anatomy. Muscular activities are novel features that are highly representative of facial ...
