This paper presents a new symbol-rate timing recovery approach based on adaptive interpolation to reduce the sampling frequency of analog-to-digital converter (ADC) and power consumption for low-energy high-speed wireless communication system, such as ultra-wideband (UWB) system. Using a principle of maximum absolute-squared sum (MASS), the ADC can select the optimal clock phase provided by a m...

We give a modification of minimal residual iteration MR , which is 1V-DSMR to solve the linear system Ax b. By analyzing, we find the modifiable iteration to be a projection technique; moreover, the modification of which gives a better at least the same reduction of the residual error than MR. In the end, a numerical example is given to demonstrate the reduction of the residual error between th...

BACKGROUND Minimal residual disease is an important independent prognostic factor in childhood acute lymphoblastic leukemia. The classical detection methods such as multiparameter flow cytometry and real-time quantitative polymerase chain reaction analysis are expensive, time-consuming and complex, and require considerable technical expertise. DESIGN AND METHODS We analyzed 229 consecutive ch...

We consider the problem of policy evaluation in a special class of Markov Decision Processes (MDPs) where the underlying Markov chains are large and sparse. We start from a stationary model equation that the limit of Temporal Difference (TD) learning satisfies, and develop a Robbins-Monro method consistently estimating its coefficients. Then we introduce the minimal residual approaches, which s...

The residual echo enhancement (REE) procedure proposed in [1] is able to improve the acoustic echo cancellation (AEC) performance in a very noisy acoustic mixing environment by utilizing the natural learning ability of the least-mean square (LMS) algorithm without precise estimation of the signal statistics. We demonstrate in this paper that the technique can also be applied effectively in a mu...

In seepage problems, the coefficients of permeability in Laplace equation are usually assumed to be constant vs. both space and time; but in reality these coefficients are variable. In this study, the effect of material deformation due to external loads (consolidation) and variation of head in the consolidation process are considered. For the first case, formulation of kx and ky can be defined ...

in this paper, least square method (lsm) and differential transformation method (dtm) are used to solve the problem of laminar nanofluid flow in a semi-porous channel in the presence of transverse magnetic field. due to existence some shortcomings in each method, a novel and efficient method named ls-dtm is introduced which omitted those defects and has an excellent agreement with numerical sol...

Determination of mobile localization with time of arrival (TOA) signal is a requirement in cellular mobile communication. In some of the previous methods, localization with non-line-of-sight (NLOS) paths can lead to large position error. Also for simplicity, in most simulations suppose non stationary actual environments as stationary. This paper proposes (residual test + recursive least square)...
