ABSTRACT
The basic idea of cooperative communication is that each single-antenna user is considered as a relay node which forwards information for each other. Common forward manners are amplify-forward (AF) and decode-forward (DF). In AF manner, relay node only amplifies the power of its received signal from source, and then destination decodes its received signal from the relay. In DF manner, relay node decodes its received signal from source and then transmits to the destination.
