multipath propagation

Antenna diversity is especially effective at mitigating these multipath propagation situations.

Multipath propagation, particularly reflection from indoor walls and surfaces, causes serious fading.

SFN transmission can be considered as a severe form of multipath propagation.

As opposed to multipath propagation, bandlimited channels are present in both wired and wireless communications.

Challenges to telemetering this data include fading, multipath propagation and the Doppler effect.

Multipath propagation is inevitable with wireless systems.

As well such mapping will support the systematic and well determined consideration of multipath propagation effects.

This helps overcome multipath propagation, as at least some of the frequencies have a line-of-sight trajectory.

A: Gaussian channel with very little multipath propagation and Doppler effect.

An attractive aspect of time reversal signal processing is the fact that it makes use of multipath propagation.

They then diffract over roof edges into the street, where multipath propagation, absorption and diffraction phenomena dominate.

However, conventional beams are not a good analogy in cellular networks, which are mainly characterized by multipath propagation.

B: multipath propagation channel.

The more the guard interval is the more the system is resistant to long multipath propagation (delay spread).

Typical issues with multipath propagation are fading, dither, diffraction, combining as non-linearity effects for the distance model.

However, there is still multipath propagation and inter-pulse interference to fast-pulse systems which must be mitigated by coding techniques.

Multipath propagation may also happen in wired media, especially in cases in which impedance mismatches cause signal reflections.

Robust against intersymbol interference (ISI) and fading caused by multipath propagation.

Early ATSC tuners were not very good at handling multipath propagation, but later systems have seen significant improvements.

Diversity techniques may exploit the multipath propagation, resulting in a diversity gain, often measured in decibels.

In case of only fast fading due to multipath propagation, its amplitude may have Rayleigh distribution or Ricean distribution.

It is frequently used with coherent modulations such as phase shift keying, mitigating the effects of multipath propagation and Doppler spreading.

Multipath propagation is achieved by inducing multiple simulated electromagnetic paths digitally thus producing signal fading and audio distortion.

Rich multipath propagation decreases the spatial correlation by spreading the signal such that multipath components are received from many different spatial directions.

ISI is usually caused by multipath propagation or the inherent non-linear frequency response of a channel causing successive symbols to "blur" together.
