A cooperative relaying. system with transmission scheduling is investigated Cooperative relaying, is composed of multiple links because the source;ends the data to more than one receiver, and the destination receive; multiple data transmitted by more than one transmitter Therefore. tithe source can transmit the data when the channel gains of the links are high, it is not clear which channel gains should he high in order to achieve high spectral efficiency In the present letter. the spectral efficiency of a cooperative relay me system is theoretically derived under the assumption that the source transmits the data only when the channel gains of links are above certain threshold values Numerical results reveal that a high spectral efficiency can be achieved by assuring a high channel gain for the link with the highest average received power among links to the destination.
