In this paper composite mobile environments, modeled by overlap service areas are taken for performance analysis of a wireless multiple channel link. The accurately approximated Gamma distributions is used to obtain analytical expressions for performance metrics such as average real-time miss rate and outage probability. The equivalent probability distribution function of client request to chan...

using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...

We analyze the ergodic capacity and channel outage probability for a composite MIMO channel model, which includes both fast fading and shadowing effects. The ergodic capacity and exact channel outage probability with space-time water-filling can be evaluated through numerical integrations, which can be further simplified by using approximated empirical eigenvalue and maximal eigenvalue distribu...

Westmoreland February 1, 2008 Department of Physics, Kenyon College, Gambier, OH 43022 USA Department of Mathematical Sciences, Denison University, Granville, OH 43023 USA Abstract The errors that arise in a quantum channel can be corrected perfectly if and only if the chann...

This paper focuses on the design of a multiuser receiver structure for a Code Division Multiple Access (CDMA) communication system, in the presence of multipath eeects and using an antenna array at the base station receiver. The algorithm presented in this paper solves the complex mul-tidimensional problem of channel estimation in this complex scenario using a maximum likelihood approach. Once ...

In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...

Most recent studies have supported inhibition of the renin-angiotensin-aldosterone system (RAAS) with diuretic as initial hypertensive therapy in patients with chronic kidney disease (CKD). The recommended role of calcium channel blockers (CCB) in CKD patients had diminished due to class-specific differences in antiproteinuric effects and lesser efficacy in reducing composite renal clinical out...

In a multi user communication environment such as communication satellites, inter-channel isolation is provided by channelizing/multiplexing networks that splits composite wideband signal into various narrowband RF signals corresponding to each user. In a communication satellite transponder, input multiplexing network is placed at the output of low noise receiver. It divides the composite recei...

This correspondence analyzes the performance of concatenated coding systems and modulation schemes operating over the additive white Gaussian noise (AWGN) channel by examining the loss of capacity resulting from each of the processing steps. The techniques described in this correspondence allow the separate evaluation of codes and decoders and thus the identification of where loss of capacity o...

In this paper, we analyze the performance of cooperative diversity using adaptive Decode and Forward (DF) relaying over independent but non-necessarily identical flat composite fading channels which include multipath fading and shadowing simultaneously. We have considered the transmission of M-QAM modulated signals over Generalized-K channel model which is very versatile and accurately approxim...
