Circuit models with mixed lumped and distributed elements for passive one-port devices
Şengül, Metin (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 ... -
Co-training using prosodic, lexical and morphological information for automatic sentence segmentation of Turkish spoken language
Dalva, Doğan (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 ... -
Cooperative strategies, achievable rates and resource allocation for OFDMA channels
Bakım, İsmail Sezi (Işık Üniversitesi, 2011-07-28)The design of next generation wireless communication systems brings along new challenges, since the degrading factors such as fading and multi-user interference become harder to deal with as the number of users and the ... -
Design and optimization of multiuser cooperative protocols for wireless networks
Edemen, Çağatay (Işık Üniversitesi, 2014-09-12)Recently, the main trend in wireless communications has shifted from voice transmission to data communication. Naturally, this shift caused an increase in the data rate and bandwidth requirements. Being a limited and thus ... -
Metamutator: Its Realizations and Its Applications
Minayi, Elham (Işık Üniversitesi, 2019-07-22)Mutators became very popular after 1971, when Leon Chua realized the memristor, his postulated fourth circuit element, using them. The reason for the popularity of mutators, which are easily realizable 2-port devices, lies ... -
Multiband and concurrent matching network design
Yıldız, Serkan (Işık Üniversitesi, 2020-02-05)Multiband network design has become a big issue due to the current improvements in RF and MW technologies. Since the new wireless protocols come up fast such as 3G, 4G, 5G etc., the RF and MW hardware must be designed to ... -
New approaches for channel estimation in wireless communications
Şenol, Habib (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 ... -
Ring array processing for forward-looking intravascular and intracardiac ultrasonic imaging
Tekeş, Coşkun (Işık Üniversitesi, 2010-06-08)Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in IVUS and ICE applications. One of the main challenges in the array based FLIVUS systems is the large channel count which ... -
Solid-state arrays and beamformers for side-looking intravascular ultrasonic imaging
Şişman, Alper (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, ...
