H.264 vi?deo kodlamada B-çerçeveler i?çi?n kodçözücü tarafında aday devi?ni?m vektör seçi?mi?
(IEEE, 2012-04-18)
H.264 standardında devinim vektör farklarının kodlanması sebebiyle özellikle düşük bit hızlarında nesne sınırlarında devinimdeki ani değişiklikler harcanan bit miktarlarını artırmaktadır. Bu bildiride B-çerçevelerde kod ...
Cyclostationarity-based robust algorithms for QAM signal identification
(IEEE-INST Electrical Electronics Engineers Inc, 2012-01)
This letter proposes two novel algorithms for the identification of quadrature amplitude modulation (QAM) signals. The cyclostationarity-based features used by these algorithms are robust with respect to timing, phase, and ...
Compression of ECG signals using variable-length classified vector sets and wavelet transforms
(Springer International Publishing AG, 2012)
In this article, an improved and more efficient algorithm for the compression of the electrocardiogram (ECG) signals is presented, which combines the processes of modeling ECG signal by variable-length classified signature ...
New robust stability results for bidirectional associative memory neural networks with multiple time delays
(Elsevier Science Inc, 2012-08-01)
In this paper, the robust stability problem is investigated for a class of bidirectional associative memory (BAM) neural networks with multiple time delays. By employing suitable Lyapunov functionals and using the upper ...
Equilibrium and stability analysis of delayed neural networks under parameter uncertainties
(Elsevier Science Inc, 2012-02-15)
This paper proposes new results for the existence, uniqueness and global asymptotic stability of the equilibrium point for neural networks with multiple time delays under parameter uncertainties. By using Lyapunov stability ...
An analog integrated circuit beamformer for high-frequency medical ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2012-10)
We designed and fabricated a dynamic receive beamformer integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer IC is suitable for integration with an annular array transducer for high-frequency (30-50 MHz) ...
Robust stability analysis of a class of neural networks with discrete time delays
(Pergamon-Elsevier Science Ltd, 2012-05)
This paper studies the existence, uniqueness and global asymptotic stability of the equilibrium point for the class of neural networks with discrete constant time delays under parameter uncertainties. The class of the ...
A survey of algorithms and architectures for H.264 sub-pixel motion estimation

This paper reviews recent state-of-the-art H. 264 sub-pixel motion estimation (SME) algorithms and architectures. First, H.264 SME is analyzed and the impact of its functionalities on coding performance is investigated. ...
Optimal and near-optimal partner selection algorithms in cooperative OFDMA
(IEEE, 2012)
We obtain the jointly optimal power allocation and partner selection policies, that maximize the sum rate of a cooperative OFDMA system with mutually cooperating pairs of users. We show that the power allocation and partner ...
New sufficient criteria for global robust stability of neural networks with multiple time delays
(Işık University Press, 2012)
In this paper, we study global robust asymptotic stability of the equilibrium point for neural networks with multiple time delays. By employing suitable Lyapunov functionals, we derive a set of delay independent sufficient ...
