Figure 5From: Multi-functional MIMO communication in multi-hop cellular systemsBER comparison between Alamouti-based multi-functional MIMO and QOSTBC transmission. BER comparison between Alamouti-based multi-functional MIMO and QOSTBC transmission with MS = 4, MR = 4, and d = 0.5, both evaluated with and without availability of the direct link: (a) With BPSK and QPSK, (b) with QPSK and 16 QAM.Back to article page
