In this paper, an idea of using space-time block coding (STBC) in multi-user cooperative diversity has been
exploited to improve the performance of the transmission in wireless local area networks. The theoretical
and simulation results show that, using STBC approaches can always achieve the better performance than
existing techniques without introducing the space-time coding. By analyzing the throughput and frame error
ratio (FER) of the two different STBC cooperative schemes, we find the trade-off between throughput and
reliability. The location of the relay is crucial to the performance, which supposes a rule for future crosslayer
design.
