A generalization of the Wiener-Hopf approach to direct and inverse scattering problems connected with non-homogeneous half-spaces bounded by n-part boundaries
(Oxford Univ Press, 2000-08)
The classical Wiener-Hopf method connected with mixed two-part boundary-value problems is generalized to cover n-part boundaries. To this end one starts from an ad-hoc representation for the Green function, which involves ...
Classification-based macroblock layer rate control for low delay transmission of H.263 video
(IS & T - Soc Imaging Science Technology, 2003-07)
Puri and Aravind's method of macroblock bit count estimation for video rate control is based on the classification of the macroblock data into discrete classes and assigning a unique non-linear estimate for each class and ...
A real frequency approach to describe lossless two-ports formed with mixed lumped and distributed elements
(Urban & Fischer Verlag, 2001)
The design of microwave filters, matching networks, amplifiers, that Is the "Broadband Networks" with mixed lossless lumped and distributed elements, has been a significant concern of the circuit theoreticians of the field. ...
Adaptive Kalman receiver for OFDM systems with transmit diversity in mobile wireless channels
(Walter De Gruyter GMBH, 2004-12)
A new joint channel tracking and symbol detection scheme is proposed in this paper for pilot symbol assisted transmit diversity OFDM systems by exploiting the correlation of the adjacent subchannels. Modelling the channel ...
Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane
(Elsevier Science BV, 2005-06)
During the second half of the last century mixed boundary-value problems had been an appealing research subject for both mathematicians and engineers. Among this kind of problems those connected with wave propagation in ...
On the effects of random timing jitter on spectrum sensing algorithms based on cyclostationarity
(IEEE, 2009)
Cognitive radio is an enabling technology, which is expected to lead to a more efficient utilization of the available spectral resources due to its flexibility and its ability to sense its spectral environment. Recently, ...
On the effect of random sampling jitter on cyclostationarity based spectrum sensing algorithms for cognitive radio
(IEEE, 2009)
Cognitive radio is an enabling technology, which is expected to lead to a more efficient utilization of the available spectral resources due to its flexibility and its ability to sense its spectral environment. Recently, ...
Video çerçeve hız artırımında kapatma yapaylıklarının giderilmesi
(IEEE, 2009-06-26)
Çerçeve hız arttırımı (ÇHA) yöntemleri, önceleri video standartları arası dönüşümlerde kullanılmış günümüzde ise büyük ekran LCD ve plazma Tv setlerinde daha kaliteli görüntü için sayısal video yayınının zamansal çözünürlüğünün ...
A novel method to represent the speech signals by using language and speaker independent predefined functions sets
(IEEE, 2004)
In this paper a new modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={s(R)(t)} and Envelope Function E = {e(K)(t)} Sets (PSEFS). These ...
Cascade synthesis of two-variable lossless two-port networks with lumped elements and transmission lines: a semi-analytic procedure
(Tylor & Francis Ltd, 2001)
Two-variable characterization of cascades composed of lossless two-port networks with lumped elements and transmission lines is considered. The problems associated with the construction of scattering functions in two ...
