What is multipath propagation in wireless communication?
Multipath propagation, an inherent feature of a mobile communications channel, results in a received signal that is dispersed in time. Each path has its own delay and the time dispersion leads to a form of intersymbol interference. Delay spread is a measure of the multipath profile of a mobile communications channel.
What is multipath propagation explain how it affects signal quality?
When the same signal is received over more than one path, it can create interference and phase shifting of the signal. Destructive interference causes fading; this may cause a radio signal to become too weak in certain areas to be received adequately.
What is signal propagation in wireless communication?
1. This is the movement of radio waves from a transmitter to a receiver. When the waves travel (propagate) from one point to another, they are, like light waves, affected by different phenomena such as light reflection, absorption, or scattering.
What are the three basic propagation mechanisms?
The main NLOS propagation mechanisms are reflection, scattering, and diffraction.
