  • In this paper, a new type of Space-Time Block Code (STBC) that is similar to ABBA code is expanded and utilized in CD(Cooperative Diversity) networks. The decomposable character and destructive influence of non-orthogonality of this code is evaluated. The constraint of the number of cooperative nodes and the trade off of which and receive performance is investigated with simulation. The result shows that, for the cooperative communication system this paper proposed, it is enough for 8 relay nodes to participate in cooperation and more relay nodes have little effect on the system performance improvement.
