Effects of Propagation Delay on Signal Transmission
نویسنده
چکیده
As radio signals are propagated through the atmosphere, they are affected mostly by variability in refractive index which, in turn, leads to a decrease in their speed of propagation. This will eventually bring about a delay called propagation delay . Propagation delay could be viewed in various forms, but this paper has concentrated on ionospheric and tropospheric propagation delays. These delays must be properly estimated so as to be able to determine the efficiency of the transmitting and receiving antenna systems to be used. This paper therefore reviewed the theory of propagation delay caused by some atmospheric constituents. (

متن کاملDesign Supplementary Controller Based on Stabilizing Effect of Delay for Damping Inter Area Oscillations in a Power System
The delay associated with signal transmission through the wide-area measurement system reduces the functionality of the power oscillation damping control system. One of the important issues is the poor operation of the supplementary controller against delay existence, which limits the efficiency of damping of ancillary equipment, such as SVCs in a power system. This paper as a solution proposes...
