This enlarges the distance at which selective fading occurs.
2.
Thus, frequency-selective fading and phase distortion can be easily counteracted.
3.
This is true especially on High frequency radio circuits where selective fading is present.
4.
Selective fading causes the mark signal amplitude to be randomly different from the space signal amplitude.
5.
Selective fading, or Rayleigh fading can cause two carriers to randomly and independently fade to different depths.
6.
In multi-diversity, e . g ., to mitigate frequency-selective fading or narrowband interference.
7.
OFDM divides the wideband signal into many slowly modulated narrowband subcarriers, each exposed to flat fading rather than frequency selective fading.
8.
Frequency-selective fading channels are also " dispersive ", in that the signal energy associated with each symbol is spread out in time.
9.
With transmit diversity, multiple antennas transmit delayed versions of a signal, creating frequency-selective fading, which is equalized at the receiver to provide diversity gain.
10.
Selective fading manifests as a slow, cyclic disturbance; the cancellation effect, or " null ", is deepest at one particular frequency, which changes constantly, sweeping through the received audio.
