Digital color halftoning
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
Digital color halftoning is done to create the perception of a continuous-tone color image using the limited spatiochromatic discrimination capability of the human visual system. Several techniques to perform this task are ...
Window and backwards decoding achieve the same sum rate for the fading cooperative Gaussian multiple access channel
(IEEE, 2006)
For a two user fading Gaussian multiple access channel with user cooperation, we show that window decoding achieves the same sum rate as backwards decoding, when the encoding is done using block Markov superposition coding. ...
An efficient ECG data compression technique based on predefined signature and envelope vector banks
(IEEE, 2005)
In this paper, a new method to compress ElectroCardioGram (ECG) Signal by means of "Predefined Signature and Envelope Vector Banks-PSEVB" is presented. In this work, on a frame basis, any ECG signal is modeled by multiplying ...
A priority based packet scheduler with deadline considerations
(IEEE Computer Soc, 2006)
QoS issues have become a focal point of research on Next Generation Networks (NGNs). In order to supply the various QoS requirement for different kinds of applications, new scheduling policies need to be developed and ...
Design of real-time VBR traffic shaping schemes by considering the impact of both buffer overflows and deadline violations
(Int Inst Informatics & Systemics, 2005)
While smoothing the traffic of time sensitive applications at the user premises can reduce the losses due to buffer overflows within the network, it may have an adverse effect on the losses due to the deadline violations ...
Gerçel ve karmaşık süzgeç öbeklerinin eşdalgacıklı tasarımı
(IEEE, 2006-07-31)
Bu bildiride, eşdalgacıklı tam geri çatma süzgeç öbekleri tasarlamak için, Parks-McClellan algoritması gibi tekniklerle üretilen enküçük-enbüyük optimal eşdalgacıklı kısıtsız süzgeçleri eşlemlemede kullanılan basit bir ...
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 ...
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 ...
Achieving the capacity region boundary of fading CDMA channels via generalized iterative waterfilling
(IEEE, 2006-11)
We characterize the optimum power control policies that achieve arbitrary rate tuples on the boundary of the, capacity region of a power controlled, code division multiple access (CDMA) system in a fading channel with ...
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH, 2006)
Modeling the frequency selective fading channels as random processes, we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ...
