In this paper we propose the application of an autoregressive moving-average (ARMA) model to create a digital filter which closely matches the Jakes-Reudink autocorrelation function of a frequency-nonselective multipath fading environment [1]. This involves a least squares calculation

This paper presents an architecture of Multiband Impulse Radio UWB (MB-IR-UWB) system based on Prolate Spheroidal Wave Function (PSWF) by binary time hopping pulse position modulation (TH-PPM) over multipath fading channel. In order to combat multipath fading, Rake receiver using maximal ratio

A set of parameters collectively called re-centered (RC) normalized mean square correlation (NMSR) is introduced to characterize the quality of multipath fading channels with non-zero specular components. The consideration of non-zero specular components requires non-trivial generalization

In this paper, we analyze the geometry of signals for multipath fading channels and their resistance to a non-linear transmitter. We do this by defining an orthonormal signal space as the eigenfunctions of the channel and the non-linearity is modeled as an amplitude clipping device. In addition, we

This work studies the capacity of multipath fading channels. A noncoherent channel model is considered, where neither the transmitter nor the receiver is cognizant of the realization of the path gains, but both are cognizant of their statistics. It is shown that if the delay spread is large

Multipath fading heavily contributes to the unreliability of wireless links, causing fairly large deviations from link qual-ity predictions based on path loss models; its impact on wire-less sensor networks is considerable. Although analytical models provide a probabilistic description, multipath

Abstract—We investigate the multipath fading relay channel in the limit of a large bandwidth, and in the non-coherent setting, where the channel state is unknown to all terminals, including the relay and the destination. We propose a hypergraph model of the wideband multipath fading relay channel

In this paper we will investigate the capacity and mutual information of a broadband fading channel consisting of a finite number of time-varying paths. We will show that the capacity of the channel in the wideband limit is the same as that of a wideband Gaussian channel with the same average

this paper, we propose an adaptive subband array with DFT filter banks for multipath fading mitigation in land mobile communications. The purpose is to improve convergence of the desired signal equalization as well as to effectively suppress the interferers. A DFT filter bank transforms
