摘要：
In this paper we explore in a multicarrier system with different orthogonal spreading types two transmit diversity schemes, namely the Alamouti scheme and cyclic delay diversity. We compare both in different channel scenarios and also vary the interleaving for the spread data symbols. Finally, we show how to overcome the limits of orthogonal space-time block codes of orthogonal designs by combining the Alamouti scheme with the cyclic delay diversity scheme.
