In this paper,the wireless communication system with dual SC receiver operating over shadowed multipath fading channel is considered. The multipath fadingis k-μor Rician.The received signal experiences the short term fading which is resulting in SC receiver envelope variation and Gamma long term fading resulting in SC receiver envelope power variation. The closed form expressions for joint probability density functions of SC receiver output signal envelope and their first derivative of SC receiver output signal envelope are calculated for both, k-μand Rician fading. These expressions are used

Abstract Bertrand Russell abandoned the notion of acquaintance in July 1918. What changes does this force in his account of the mind? This paper focuses on one puzzle of interpretation about this. In 1913, Russell offered an account of ‘egocentric particulars’, his term for indexicals and demonstratives. He argued that the fundamental objection to neutral monism was that it could not provide an adequate theory of these terms. In 1918, Russell now embraces a form of neutral monism, but he does not return to the problem of indexicals until 1940 in his William James lectures. Is the account given

These fading create severe problems in long distance wireless systems where multipath fading is superim-posed on shadowing fading (called multipath-shadowing fading).

This article addresses a novel real-time locating system for localization of high-speed mobile objects in fading environments. The proposed locating system exploits time difference of arrival measurements based on ultra-wideband signals. However, the ultra-wideband signals cause a frequency-selective fading due to their short time duration, which induces severe inter-symbol interference. Moreover, high-speed objects cause fast fading due to large Doppler spread. Therefore, the fading cases considerably reduce the localization performance. The presented locating system relies on a new localizat

The other solution is to use an alternative statistical behavior of fading channels (applying the basic concepts of diversity), which use two or more inputs on the receiver to ensure the correlation of signal.

<strong>Abstract: </strong>   <strong>Objective-</strong><strong> </strong>In this paper, for cognitive radio networks (CRN) the detection range over different fading channels has been detected which is the key parameter for the better performance of intelligent wireless communication systems. For efficient communication system, the impact of fading medium should be examined on the detection range. Analytical expression for the probability of missed detection and detection range over Rayleigh, Weibull and Laplace fading channels with superimposed lognormal shadowing in cognitive radio net

Abstract. Rapid fading of auroral activity a few minutes before substorm breakup has earlier been analyzed in case-studies. Here we report on a study in which all-sky camera (ASC) and magnetic data over 3 years were examined to find breakups that were accompanied by a preceding fading. To illustrate typical features of the fading effect we analyze three events in detail and discuss seven other events to find the spatial and temporal behavior of the fading and the global conditions favoring this phenomenon, which is not associated with every breakup. In these ten events the precipitation dimini

In this paper, we consider wireless mobile radio communication system with macro diversity reception. Signal is subject to Weibull small scale fading and Gamma large scale fading resulting in system performance degradation. Receiver uses macro diversity selection combining (SC) technique in order to reduce the impact of long term fading effects, and two micro diversity SC branches are used to mitigate Weibull short term fading effects on system performance. Probability density function (PDF), and cumulative distribution function (CDF), as well as level crossing rate (LCR) and average fade dura

The volcanic origin of the sediments from Sulawesi, Indonesia, provides a particular challenge for luminescence dating due to the dim optically stimulated luminescence (OSL) from quartz, and the high anomalous fading rate in the infrared (IR) stimulated luminescence (IRSL) from feldspars. In this study, we present results of dating the sanidine feldspars from 2 samples taken from an archaeological site (Leang Bulu Bettue) in the Maros karsts of South Sulawesi. We tested the post-IR IRSL (pIRIR) procedures in order to find a stable luminescence signal that is less affected by anomalous fading.

In this paper, a novel algorithm based on the combination of a fading filter (FF) and an extreme learning machine (ELM) is presented for Global Positioning System/Inertial Navigation System (GPS/INS) integrated navigation systems. In order to increase the filtering accuracy of the model, a variable fading factor fading filter based on the fading factor is proposed. It adjusts the fading factor by the ratio of the estimated covariance before and after the moment which proves to have excellent performance in our experiment. An extreme learning machine based on a Fourier orthogonal basis function

Orthogonal frequency division multiplexing (OFDM) is a type of multicarrier modulation (MCM) technique in which larger bandwidth is divided into parallel narrow bands each of which is modulated by different subcarriers. All the subcarriers are orthogonal to each other and hence it reduces the interference among various subcarriers. OFDM technique is an efficient modulation technique used in certain wired and wireless application.In a wireless communication channel, the transmitted signal can travel from transmitter to receiver over multiple reflective paths. This results to multipath fading wh

The main problem with the radio-over-fiber (RoF) link is the decrease in the recovered radio frequency (RF) power due to the chromatic dispersion of the fiber known as dispersion power fading. One of the methods for dealing with dispersion power fading is to use the optical single sideband (OSSB) modulation scheme. The OSSB modulation scheme can be generated by biasing the dual-drive Mach–Zehnder modulator (DD-MZM) to the quadrature bias point (QBP) and shifting the RF drive signal phase (θ) by 90°, which is called the regular θ. However, the OSSB modulation scheme only overcomes dispersion po
