A multiple input multiple output (MIMO) system presents the disadvantage that the system has high cost if receiver size is limited. A cooperative communication system overcomes disadvantages of MIMO system. So, many cooperative communication transmission schemes have been studied. In this paper, the proposed scheme considers channel condition of source to destination and then decides on a usage for channel coding. The channel coding is used for transmission in badly conditioned channel to improve the performance. If channel condition is good, the channel coding is not used, whet increases the throughput. The channel condition is determined using the cyclic redundancy check code. The simulation results show that the proposed scheme has better trade-off between the performance and throughput than the conventional scheme.
