Sentence examples for spread of propagation from inspiring English sources
The estimator performs energy integrations successively with long time duration comparable to the delay spread of propagation channel.
These sub-bands have relatively small angle spread of propagation paths which leads to high spatial correlation even in microcells, in which the root mean square (RMS) angle spread per propagation path (sub-band) is typically in the range of 5° [10].
As (8) shows the spatial correlation can be evaluated analytically for different angular distributions of the power azimuth spread (PAS) of propagation paths as long as the antenna radiation patterns are known.
The urban microcell environmental model was applied since it is most feasible for high data rate MIMO applications due to its wide angular spread (AS) of propagation paths and relatively short distances between users and the base station.
The symbol is typically preceded by the GI whose duration is longer than the delay spread of the propagation channel.
At both ends, the spatial correlation is determined by the power azimuth spread of the propagation paths impinging at the antenna array.
Spatial correlation in the chosen RB of the fixed beam approach (BeamCorr) and the reference antenna approach (AntCorr) as a function of Laplace distributed RMS angle spread of impinging propagation paths.
In this paper, we evaluated the effects of the delay spread of the propagation channels and the time variations in three places with different channel characteristics and verified the feasibility of DL MU-MIMO-OFDM for gigabit-per-second transmission in wireless LAN systems.
From animal and human models emerges that KD might affects CNS at multiple levels: it is able to normalize cortical dysexcitability and to reduce cortical spreading depression velocity of propagation, which mechanisms are potentially of interest in migraine pathophysiology.
These methods are of particular interest when the delay spread of the wireless propagation environment is limited.
A variety of control measures including replacing sensitive rootstocks, prevention of spread with propagation material, and wide scale use of cross-protection for handling stem pitting-related problems are now commonly used in attempts to control the range of CTV diseases.
