In this paper, fading models are considered. Fading is deviation of the attenuation of signal affecting certain parameters and various components. In this paper, I represent the disadvantages 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 all of the signal bandwidth. Furthermore this review paper also describes its appropriate solution OFDM that will reduce fading in some extent.
