What are the effects of fading?
Fading can cause poor performance in a communication system because it can result in a loss of signal power without reducing the power of the noise. This signal loss can be over some or all of the signal bandwidth.
What is the major cause of fading?
Ultraviolet rays are one of the causes of fading because they can break down chemical bonds and fade the color in an object. Other major contributors to fading include visible light and solar heat. Some objects may be more prone to this bleaching effect, such as dyed textiles and watercolors.
What are the types of fading?
Flat Fading: In flat fading, all frequency components get affected almost equally. Flat multipath fading causes the amplitude to fluctuate over a period of time. Selective Fading: Selective Fading or Selective Frequency Fading refers to multipath fading when the selected frequency component of the signal is affected.
How fading can be minimized?
Explanation: Fast fading can be minimized by using coding and interleaving, by using robust modulation and by introducing signal redundancy to increase signalling rate.
