I. Introduction
The exponential growth of wireless network over last few decades become a challenge in the communication industry to improve the performance of the network with the high demand from users [1]. The signal transmitted from the antenna will face with fading as the signal propagated in order to reach the receiver. This signal will travel in different path with the interference of surrounding noise and distortion. Thus, the signal is fading and distorted and caused the receiver unable to retrieve the signal [2].
