Fading degrades the communication system performance due to a loss of signal power without decreasing the noise power over some or all the signal bandwidth, the received signal fluctuates, varies in intensity at each instant, increases and decreases through nulls and zeros of voltage. The probability of experiencing fading with the concomitant bit errors as the Signal-to-Noise Ratio (SNR) drops on the channel limits the link performance. Multipath fading (MF) affects most forms of radio communications links in one way or another. MF occurs in an environment where there is multipath propagation, and the paths change for some reason, resulting of propagating multiple versions of signals transmitted across different paths before they reach the receiver.
