Channel adaptive encoding and decoding strategies and rate regions for the three user cooperative multiple access channel
(IEEE, 2008)
For a cooperative Gaussian multiple access channel (MAC), we propose a new channel adaptive three user cooperation strategy, based on a non-trivial extension of block Markov super-position encoding. We obtain the expressions ...
A novel noise robust and low bit rate speech coding algorithm
(IEEE, 2009)
In this work, a new noise robust and variable length frame based speech modeling method is introduced. This method consists of three major steps which includes noise removal algorithm, coding and encoding algorithms, ...

Bu çalışmanın amacı, bağlanırlık kodlaması için gerçeklenmiş [I]'deki algoritmayı bazı yenilikler ile uygulamak ve koordinat sıkıştırması için 3-B (3 Boyutlu) nesne gösterimleri alanında kullanımı kısıtlı olan kayıplı bir ...
EM-Based sequence estimation for wireless systems with orthogonal transmit diversity
(IEEE, 2003)
In this paper, an optimum sequence estimation algorithm for wireless systems with Alamouti's two transmitter diversity in the presence of multipath fading is proposed. The algorithm is based on a jointly iterative channel ...
Hızlı sönümlemeli kanallarda yeni bir uzay-zaman-frekans kodlamalı OFDM sistem tasarımı

Bu çalışmada, frekans seçici hızlı sönümlemeli kanallarda telsiz iletişim için bir uzay-zaman-frekans çeşitlemesi yöntemi önerilmiştir. Önerilen yöntem, OFDM tekniğini kullanarak frekans seçici kanalı uygun hale getirdikten ...
Tip singularity of the electromagnetic field at the apex of a material cone
(Springer-Verlag Berlin, 2004)
The tip Singularity of the electromagnetic field at the apex of a cone is investigated in its most general framework. To this end one considers, without loss of generality, a circularly symmetric cone which separates two ...
Wavelet image coding using the spherical representation
(IEEE, 2005)
In this paper, we introduce the "spherical representation", which provides a new adaptive framework for modeling and coding the image information in wavelet subbands. Based on this representation, a practical coding algorithm ...
Channel estimation for space-time block coded OFDM systems in the presence of multipath fading
(IEEE, 2002)
In this paper, a computationally efficient, non-data-aided maximum a posterlori(MAP) channel estimation algorithm is proposed for orthogonal frequency division multiplexing (OFDM) systems with transmitter diversity using ...
QoS-constrained core selection for group communication
(IEEE, 2005)
The core-based approach in multipoint communication enhances the solution space in terms of QoS-efficiency of solutions in inter and intra-domain routing. In an earlier work [KH04], we showed that the constrained cost ...
Immitance data modelling via linear interpolation techniques
(IEEE, 2002)
With the advancement of the manufacturing technologies to produce new generation analog/digital communication systems, immitance data modelling has gained renewed importance in the literature. Specifically, models are ...
