The Effect of Multi–Fold Scattering onto the Capacity of BLAST–like Systems
نویسنده
چکیده
The linear vector–valued channel x 7! QiM ix + z with z and M i denoting additive white Gaussian noise and independent random matrices, respectively, is used to model shadowing for BLAST– like communication systems. It is analyzed in the asymptotic regime as the dimensions of the matrices and vectors involved become large by means of free probability theory. It turns out that almost all singular values of QiM i converge to zero as the number of factors tends to infinity. Index terms — channel models, fading channels, antenna arrays, shadowing, random matrices

متن کاملThe Study of Adsorption Characteristics of 1-Chloro-4-Nitrobenzene onto Multi-Walled Carbon Nanotubes Surfaces from Aqueous Solution: Equilibrium and Kinetics
In this study adsorption of 1-chloro-4-nitrobenzene (CNB) from aqueous solutions onto multi-walled carbon nanotubes (MWCNTs) was surveyed. The effect of some key parameters such as pH (2-10), carbon nanotubes dosage (0.02-0.1 mg/250mL), CNB concentration (2- 16 mg/L), and temperature (20,30,40,50°C) were investigated. The results showed that, the variation of initial pH and CNB concentration ex...

Background: Synthetic dyes are serious pollutants and wide ranges of methods have been employed for their removal from aquatic systems. We studied the adsorption of "Nile blue A" (NBA), an anionic dye, from aqueous solution by oxidized multi-walled carbon nanotubes (MWCNTs). Methods: Scanning electron microscope and Fourier transform infrared spectroscopy were used to characterize ...
متن کاملFractal-Like Kinetics Study of Adsorption on Multi-walled Carbon Nanotube
The fractal degree of adsorption on the multi-walled carbon nanotube has been investigated. The fractal-like Langmuir kinetics model has been used to obtain the fractal degree of ion adsorption on multi-walled carbon nanotube. The behavior of the fractal-like kinetics equation was compared with some famous rate equations like Langmuir, pseudo-first-order and pseudo-second-order equations. It is...
