Average Fade Duration of Triple Nakagami-m Random Process and Application in Wireless Relay Communication System

In this paper, the average fade duration (AFD) of the wireless relay communication system with three sections in the presence of Nakagami-m fading is determined and presented graphically. AFD is used to show how long a user is in continuous outage, below a specified level, after crossing that level in a downward direction. This result is useful in information theory, for example for coding design.
