Cooperative communication is a promising technology to improve the performance of resource-limited or cost-sensitive single antenna wireless equipment. Moreover, full duplex (FD) could theoretically double the spectral efficiency of a cooperative communication system comparing to the conventional half duplex (HD) communication. Although researchers have studied FD cooperative communication with two source nodes, and proposed an Alamouti-style space-time code, there is not much works on multiple source nodes scenarios yet. This article presents our results on the FD cooperative communication with multiple source nodes. We provide two orthogonal space-time block codes (OSTBC) for both three and four source nodes scenarios. The proposed codes skillfully share data in as less time slots as possible by taking advantages of the FD communication. Consequently, spectral efficiency of the FD cooperation is improved. Furthermore, the proposed codes provide full diversity in addition to a simple ML decoding. Finally, computer simulations verify the performance of the proposed OSTBC design.
