... observe. In the preceding sections, we have mentioned some of these parameters: the location of each relay; in the case of AF, the amplification gain of each relay; in the case of DF and EF, the 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 o...
