Physical-Statistical Modeling of Dynamic Indoor Power Delay Profiles

The Industrial Indoor Channel: Statistical Analysis of the Power Delay Profile

In this paper, an analysis of the wireless channel impulse response in industrial environments is presented. Only limited literature exists which investigates the multipath profile in industrial channels, e.g., [1]. In this work, measurements of the channel impulse response are fitted to the widely used Saleh-Valenzuela model [2]. Measurements have been performed to reflect a specific kind of i...

Methods for modeling of specified and measured multipath power-delay profiles

Site specific prediction and measurement of indoor power delay and power azimuth spectra at 5 GHz

This paper describes a newly developed three dimensional ray launching model for complex indoor environments. The model is capable of predicting detailed temporal and spatial multipath. To investigate and evaluate the accuracy of this model, predictions are compared with detailed measurements recently taken in an office environment. Power Delay and Power Azimuth Spectra are measured using a mul...

Wideband Diversity in Multipath Channels with Nonuniform Power Delay Profiles

The focus of this paper is to derive the symbol error probability (SEP) of a Rake receiver with a limited number of fingers that track the strongest multipath components in a frequency-selective Rayleigh fading channel. We develop an analytical framework that allows the computation of the SEP for nonuniform power delay profiles (PDPs) and spreading bandwidth. By transforming the physical Rake r...

Statistical Moment Estimation of Delay and Power in Circuit Simulation

Monte Carlo methods and simulation are often used to estimate the mean, variance, and higher order statistical moments of circuit properties like delay and power. The main issues with Monte Carlo methods are the required long run time and the need for prior detailed knowledge of the distribution of the variations. Additionally, most of available circuit simulation tools can run Monte Carlo anal...
