This paper presents a decentralized kernel density estimation (KDE) technique for computing the actual positional density of the robots in a distributed network, which constitutes the feedback in the robot’s control law. The goal of the feedback control law is to plan the paths of a distributed robot network in order to follow a known, optimal time-varying robot distribution or probability dens...

© 2010 ETRI Journal, Volume 32, Number 3, June 2010 In this letter, we analyze the error performance of a mobile communication system with microdiversity and macrodiversity reception in gamma-shadowed Rician fading channels for a binary differential phase-shift keying modulation scheme. Analytical expressions for the probability density function (PDF) and moment-generating function (MGF) are de...

In dual-hop multi-relaying wireless systems, the non-closed form expression in log-normal probability distributions and high varying standard deviations makes it impossible to effectively execute performance analyses of outage probability and bit-error-rate (BER) performance levels; thus, an analysis framework was proposed for use in a composite (Rayleigh plus log-normal) fading channel. Develo...

A ratio distribution or quotient distribution is a probability distribution constructed as the distribution of the ratio of random variables having two other known.taining to a variety of product and quotient forms of random variables.

The word error rate (WER) of soft-decision-decoded binary block codes rarely has closed-form. Bounding techniques are widely used to evaluate the performance of maximum-likelihood decoding algorithm. But the existing bounds are not tight enough especially for low signal-to-noise ratios and become looser when a suboptimum decoding algorithm is used. This paper proposes a new concept named square...

In this correspondence we presents the performance analysis of multiple-input multiple-output (MIMO) technique incorporating maximal-ratio combining with transmit antenna selection (MRC/TAS) in frequency-flat Rayleigh fading channels. The expression of probability density function (pdf) for MRC/TAS (Nt , 1; Nr) scheme has been derived. The probability of outage is examined first. Further by the...

In this paper, we propose an exact analytical technique to evaluate the average capacity of a dual-hop OFDM relay system with decode-and-forward protocol in an independent and identical distribution (i.i.d.) Rayleigh fading channel. Four schemes, (no) matching “and” or “or” (no) power allocation, will be considered. First, the probability density function (pdf) for the end-to-end power channel ...

The probability density function (PDF) of the surface electromyogram (EMG) signals has been modelled with Gaussian and Laplacian distribution functions. However, a general consensus upon the PDF of the EMG signals is yet to be reached, because not only are there several biological factors that can influence this distribution function, but also different analysis techniques can lead to contradic...

We consider the tails of probability density function (PDF) for the velocity that satisfies Burgers equation driven by a Gaussian large-scale force. The saddle-point approximation is employed in the path integral so that the calculation of the PDF tails boils down to finding the special field-force configuration (instanton) that realizes the extremum of probability. For the PDFs of velocity and...

Orbit determination in application to the estimation of impact probability has the goal of determining the evolution of the state probability density function (pdf) and determining a measure of the probability of collision. Nonlinear gravitational interaction and non-conservative forces can make the pdf far from Gaussian. This work implements three nonlinear sequential estimators: the Extended ...
