What is the multipath spread of the channel?

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 are the parameters of multipath propagation?

Physically, multipath propagation parameters are multipath number, amplitude, path-length difference (delay), Doppler shift and arrival angle.

What is multipath in antennas?

Multipath is the arrival of a transmitted signal at a receive antenna from multiple paths due to reflections. The reflections can occur from the ground, trees, buildings, people, or whatever is around.

What is multipath in radar?

In radio communication, multipath is the propagation phenomenon that results in radio signals reaching the receiving antenna by two or more paths.
