In this paper we examine the performance of a satellite-terrestrial cooperative wireless network. We proposed a new grouping method, called pilot-based grouping method, to implement the space-time code in the satellite-terrestrial networks. The proposed method increases the total system channel capacity, and also saves unnecessary transmission power for the terrestrial stations. The proposed method focuses on finding out the best two signals coming from its neighboring terrestrial stations and uses the advantage of space diversity to improve the effect of channel fading. The numerical results show that the performance of ours proposed method is better than traditional grouping method.
