Tight Bounds for Ergodic Capacity of Cooperative Relaying over Rayleigh Fading Channels
Computational Intelligence and Communication Networks, 2014, Pages 313-316.
In this letter, a closed-form expression for the exact ergodic capacity of decode-and-forward (DF) systems is derived. Since the closed-form expression includes exponential integral functions and is not mathematically tractable, we simplify the expression by using Taylor series to obtain the lower and upper bounds of the ergodic capacity....More
