Description: In this paper the reduction of Intersymbol Interference
(1 ) in mobile communication channels is addressed. A
well known technique for IS1 reduction is adaptive equalization
in which the time-varying characteristics of the mobile
channel is tracked by an adaptive algorithm. We compare
different adaptive strategies and equalizer structures with
respect to overall system performance in terms of computational
complexity, numerical stability, finite wordlength
effects, size and power consumption required for VLSI implementation.

Description: This code implements automatic gain control for audio signals, which attempts to apply a smoothly-varying gain to an audio waveform in order to keep its energy close to some target level. This version also tries to balance the energy in individual frequency bands. It works by taking the short-time Fourier transform of the signal, smoothing that energy using time and frequency scales specified as arguments, then dividing out that scaled energy

Description: Identification and Tracking of Rapidly Time Varying Mobile Channels for Improved Equalization.The goal of this paper is to
investigate the effectiveness of this channel tracking method when applied to rapidly fading channels. It is shown that, by appropriately
modifying the channel estimation and equalization procedures, the
same benefits as in a slow fading system can be obtained. Simulation results demonstrate the improved performance resulting from the use
of channel tracking in rapidly time varying channels.

Description: 我们提出一种新方法用于单幅图像的空间变化模糊识别,在图像中的每个局部小块，这个局部模糊被选择在一个候选PSFS有限集中间，用一个极大似然方法。我们打算用广义似然减少参数的数量，用广义奇异值分解限制计算值，但是要对图像做出适当的边界假设。-We present a new approach for spatially varying blur identification
using a single image. Within each local patch in the
image, the local blur is selected between a finite set of candidate
PSFs by a maximum likelihood approach. We propose
to work with a Generalized Likelihood to reduce the number
of parameters and we use the Generalized Singular Value Decomposition
to limit the computing cost, while making proper
image boundary hypotheses. The resulting method is fast and
demonstrates good performance on simulated and real examples
originating from applications such as motion blur identification
and depth from defocus.

Description: Abstract A particle swarm optimization method with nonlinear
time-varying evolution (PSO-NTVE) is employed in
designing an optimal PID controller for asymptotic stabilization
of a pendubot system. In the PSO-NTVE method,
parameters are determined by using matrix experiments
with an orthogonal array, in which a minimal number of
experiments would have an effect that approximates the full
factorial experiments.

Description: hierarchical Archimedean copulas (HAC) for the US, the German and the Japanese stock market.(financial contagion is modelled by means of hierarchical Archimedean copulas (HAC) for the US, the German and the Japanese stock market. The time-varying nature of the copula parameters is induced by adopting the local parametric approach introduced in Spokoiny (1998).testing procedure underlying this approach are simulated on the basis of some predefined copula parameter constellations.)
