On spatial power gradients
نویسندگان
چکیده
The variation of the instantaneous power versus distance for a narrowband channel is an important parameter in modern digital systems, relevant for variations during a burst and for power control algorithms. This paper gives the statistical distribution for the power gradient, both in decibels and in natural units for a Rayleigh fading channel. The former has been known for some time to be Student's distributed, and the latter has a Laplacian distribution, a new result. Both results are proven here. They are in variance with an approximation given in a recent publication.

The spatial structure of cities has been one of the influential elements in the development of cities in different periods.In the cities of Iran,the spatial structure of cities is sometimes organic and during the lifetime of cities ,based on the requirements of the times,such as socio_social needs and their religious-religious ideology,and in many cases,this structure is based on programs and g...
متن کاملEffect of Raindrops Impact on Hydraulic Properties of the Rill Flow under Slope Gradients
Few studies have been done regarding the role of the raindrop in the hydrodinamic mechanism of soil erosion. In this study, rainfall simulation experiments were conducted to evaluate the role of raindrop in runoff discharge, sediment concentration and hydraulic properties of flow under four slope gradients (5, 10, 15 and 20%) in a clay soil using a 90 mm.h-1 rainfall intensity to reach the stea...

متن کاملActive control of simply supported cylindrical shells using the weighted sum of spatial gradients control metric.
It is often desired to reduce sound radiated from cylindrical shells. Active structural acoustic control (ASAC) provides a means of controlling the structural vibration in a manner to efficiently reduce the radiated sound. Previous work has often required a large number of error sensors to reduce the radiated sound power, and the control performance has been sensitive to the location of error s...
متن کاملDistance Transform Gradient Density Estimation Using the Stationary Phase Approximation
we prove a novel result using the higher-order stationary phase approximation: we show convergence of the normalized power spectrum (squared magnitude of the Fourier transform) of the wave function to the density function of the distance transform gradients as the free parameter τ → 0. In colloquial terms, spatial frequencies are gradient histogram bins. Since distance transform gradients carry...
متن کاملChemoattraction and chemotaxis in Dictyostelium discoideum: myxamoeba cannot read spatial gradients of cyclic adenosine monophosphate
Myxamoebae of the morphogenetic cellular slime mold Dictyostelium discoideum are thought to be able to accurately read and respond to directional information in spatial gradients of cyclic AMP. We examined the spatial and temporal mechanisms proposed for chemotaxis by comparing the behavior of spreading or evenly distributed cell populations after exposure to well-defined spatial gradients. The...
