... scheme in this subsection. For gaining insight into the power allocation based on minimizing the SER, we are going to minimize the approximate MGF of the random variable γ, obtained in (51). Using ... Relaying through AF DSTC In this section, we propose power allocation schemes for the AF distributed space-time codes introduced in [7], based on maximizing the receive...

... links between the sources and destinations and there are two dedicated relays (one for each source-destination pair) implementing DF. The power allocation game consists in sharing the user’s power ... non-coordinated and interfering pairs of terminals. For example, relays could be introduced by an operator aiming at improving the performance of the communications of his customers....
