Abstract	In this paper, we propose a new scheme which achieves full data rate based on DF (decode-and-forward) cooperative transmission scheme. The proposed scheme based on time division multiplexing (TDM) for channel access. When DF protocol has maximum data rate, it can not obtain diversity efficient under the pair wise error probability (PEP) viewpoint. If it increases timeslot to gain diversity efficient, then data rate is reduced. Our proposed algorithm uses orthogonal frequency and constellation rotation to obtain both full data rate and diversity order of 2. Simulation results reveal that the cooperation can save the network power up to 7dB over direct transmission at BER of $10^{-2}.$ Besides it can improve date rate of system compared with that of the conventional DF.
