Probability density functions for analyzing multi-amplitude constellations in Rayleigh and Ricean channels

IEEE Transactions on Communications, 1999
This paper derives probability density functions (PDFs) to describe the behavior of data demodulated with imperfect channel estimation. The PDFs apply to cases of flat Rayleigh-fading, multiple-diversity reception Rayleigh-fading, and flat Ricean-fading.

Quantizing Characteristics for Signals Having Laplacian Amplitude Probability Density Function

IEEE Transactions on Communications, 1978
The optimum (minimum mean-squared-error criterion) and optimum uniform quantizer characteristics for signals characterized by the Laplacian amplitude probability density function are given in tabular form. These results correct and extend previously published results.

A new amplitude probability density function estimation method for IPIX Grimsby data

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
This paper performs a fundamental analysis and a new amplitude probability density function (PDF) estimation of experimental data collected by McMaster University IPIX radar at Grimsby. Results demonstrate advantages of the new method over convenient regular histogram PDF estimation.

Variable Amplitude Loading Strains Data Distribution Using Probability Density Function and Power Spectral Density

Key Engineering Materials, 2011
This paper presents a relative study on variable amplitude (VA) strain data distribution using the approach of probability density function (PDF) and power spectral density (PSD). PDF is a technique to identify the probability of the value falling within a particular interval, and a PSD is to measure the power of a signal by converting it from the time

Probability density function of the equivalent stress amplitude using statistical transformation

Reliability Engineering & System Safety, 2015
Abstract The shape of a rainflow matrix is complex and cannot be approximated by a simple distribution function. In this paper, the Weibull–normal mixture distribution is used, for which the number of components and unknown parameters are required to be estimated.

Probability density function of tropospheric amplitude scintillation on a satellite link

4th National Conference of Telecommunication Technology, 2003. NCTT 2003 Proceedings., 2003
This paper presents the result of measurement studies of amplitude scintillation on moderate-elevation satellite path at the Ku-band. The prediction models for tropospheric scintillation on Earth satellite paths from the ITU and Gaussian are compared with measurement results from USM, Parit Buntar at frequency of 12.255 GHz and elevation angle of 40.1 ...

Optimal Quantization by Use of an Amplitude-Weighted Probability-Density Function for Diffractive Optical Elements

Applied Optics, 2004
We present a method for determining the optimal quantitized phase levels for phase-only diffractive optical elements by taking into account a modified probability-density function (PDF). This modified PDF was obtained from the PDF of the phase distribution weighted by the incident amplitude distribution.
