Abstract

Optimal power allocation for pure relay networks utilizing repetition codes has drawn a great deal of attention. However, power allocation in a cooperative network, where users who act as relays for each other and who utilize non-trivial codes, remains a challenge. With the aid of theoretical frame error rate expressions, we explore the performance of adaptive power control for decode-and-forward (DF) collaborative networks containing M users, employing turbo codes over statistically similar Rayleigh block faded channels. We conclude that power control can greatly benefit a DF collaborative network in a block fading environment.
