Sažetak
In this paper we present a new simple cooperative scheme for achieving 4th order diversity. The proposed scheme is compared with simple cooperative schemes with virtual orthogonal space time block coding (OSTBC) and quasi orthogonal space time block coding (QOSTBC). Every of these three schemes includes one base station with two antennas, two relay stations with a single antenna and one mobile station with a single antenna. The aim of the proposed scheme is to preserve, as much as it is possible, bit error rate (BER) performance of the cooperative scheme with virtual OSTBC, but with increased code rate. It is shown that the presented scheme obviously outperforms simple cooperative scheme with virtual QOSTBC, while in comparison with simple cooperative scheme with virtual OSTBC has very similar BER performance and greater code rate.
