Joint ML timing and phase estimation in OFDM systems using the EM algorithm
(IEEE, 2000)
In this paper, a computationally efficient algorithm is presented for joint maximum likelihood (ML) timing and carrier phase estimation of OFDM systems employing M-PSK modulation scheme with additive Gauissian noise, based ...
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 ...
A reflectance-based computer aided modelling tool for high speed/high frequency communication systems
(IEEE, 2001)
A reflectance-based method is presented to model the measured or computed data, obtained from a "passive one-port physical device" by means of its Darlington equivalent. The basis of the new modelling tool rests on the ...
Representation of speech signals by single signature base function within optimum frame length
(IEEE, 2000)
Before this study, we proposed a novel method to represent signals in terms of, so called, “Signature Base Functions-SBF" which were extracted from the physical features of the waveform under consideration. SBF were ...
Calculating the VC-dimension of decision trees
(IEEE, 2009)
We propose an exhaustive search algorithm that calculates the VC-dimension of univariate decision trees with binary features. The VC-dimension of the univariate decision tree with binary features depends on (i) the ...
An incremental model selection algorithm based on cross-validation for finding the architecture of a Hidden Markov model on hand gesture data sets
(IEEE, 2009-12-13)
In a multi-parameter learning problem, besides choosing the architecture of the learner, there is the problem of finding the optimal parameters to get maximum performance. When the number of parameters to be tuned increases, ...
A bit-serial sum of absolute difference accelerator for variable block size motion estimation of H.264
(IEEE, 2009)
Bit-serial architectures offer a number of attractive features over their bit-parallel counterparts such as smaller area cost, lower density interconnection, a reduced number of pins, higher clock frequency, simpler routing ...
EEG signal compression based on classified signature and envelope vector sets
(IEEE Computer Society, 2007)
In this paper, a novel method to compress ElectroEncephaloGram (EEG) Signal is proposed. The proposed method is based on the generation Classified Signature and Envelope Vector Sets (CSEVS) by using an effective k-means ...
Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane
(2004)
Among the wave propagation problems, those connected with half-spaces bounded by sectionally homogeneous boundaries take important place because they are motivated by microwave applications. If the boundary are of three ...
Spectral coding of mesh geometry with a hierarchical set partitioning algorithm
(Spie-Int Soc Optical Engineering, 2008)
This work proposes a progressive mesh geometry coder, which expresses geometry information in terms of spectral coefficients obtained through a transformation and codes these coefficients using a hierarchical set partitioning ...
