multipath

(1) See multipath routing.

(2) A radio signal that winds up taking two or more paths because the signal is reflected off buildings or other obstructions. Although multipath is a problem with all kinds of radio transmission, ghosts on a TV channel are an example of multipath that you can see with your own eyes. See antenna diversity.

Reference [26] proposes the following distributions for different fading types: Gaussian distribution with mean equal to the RSS mean for flat fading; Log-normal distribution for slow fading due to shadowing effects; Rayleigh or Ricean distribution for fast fading due to multipath propagation.
However, in consideration of the requirement of low computational complexity, for high-speed moving reception, accurately obtaining channel's FIR by using CS based methods is still a big challenge due to severe interference from Doppler frequency shift and multipath propagation.
The signal's noise-like properties protect against interference, relieve multipath propagation, and allow sharing of bandwidth with other users.
MIMO-OFDM exploits multipath propagation, an inherent feature of all wireless communications environments, delivering greater throughput, range, and reliability.
The basic effects of the multipath propagation on digital communications links are also introduced.
The sea surface reflections and other ships reflections are considered in exploring the multipath rms delay spread in fishery fleet communication environment by employing the stochastic ray method to measure maritime wireless radio multipath propagation properties, by utilizing lattice grid to describe the maritime fishery fleet propagation scenario and using Brownian bridge process to construct the basic statistical properties of random variables and by numerical simulation to obtain the rms delay spread value.
In data networks, errors occur due to interference with other users, due to multipath propagation of the signal, or due to component noise of the receiver.
Unavailability investigation of 6 GHz line-of-sight (LOS) radio links in Poland due to multipath propagation was presented in [2].
are calculated not by use of any numerical transformation from the FD solution or numerical approximation of the TL network, but through analytical elaboration of the multipath propagation process that forms the actual (physical) response mechanism, so that:
The reason for this interest can be attributed to the negative effect of the multipath propagation on the received signal quality.
