User Cooperation is a promising technology to obtain diversity gain at terminals. According to the traditional decode-and-forward scheme, relay node help to transmit source node's information with fixed number of modulation symbols all the time. It is not optimal in view of spectral efficiency, especially when the channel state is good. This paper introduces the adaptive DF scheme based on the minus...
Cooperative communication is a promising technology to obtain diversity gain at user terminals. According to the traditional coded cooperation scheme, it is hard for relay node to know the optimal number of new parity bits to relay. This paper introduces the Adaptive Coded Cooperation (ACC) scheme for accurate prediction based on the Mutual Information model. The reliability requirement is satisfied,...
