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.

In order to incorporate simultaneous influence of multipath fading and shadowing, various models have been presented recently in the literature.
It is also shown that the capacity increase of OAM waves is limited by interference incurred by multipath fading, which is even aggravated with wide beam width antennas.
Thus, the presented simulation results show that DCO-OFDM is more affected by multipath fading due to the presence of unavoidable clipping noise.
For FSM, as T-R distance increases, the accuracy of distance estimation fluctuates obviously and gradually gets worse since multipath fading. Compared with FSM, the proposed OFPEDM can significantly mitigate the multipath fading effect and reduce the negative effect on the accuracy of distance estimation.

However, multipath fading channel would seriously impact on modulation classification.
When the altitude of UAV is very low, the scatterers near the ground give strong multipath fading to the channel.
OFDM enables robust multiple access method to conflict the impairment of wireless channels, particularly of multipath fading, delay spread and Doppler shifts.
Furthermore, the platform's use of OFDM technology dampens the challenge of multipath fading and obstructions in the wireless environment.
The mobile radio signal experiences several signal variations and weakens due to multipath fading effects during transmission of data from source to destination.
In LTE-A, the quality of the received signal depends on macroscopic path loss, shadowing, multipath fading, interfering signals, and sensitivity of the receiver [1].
