  Abstract

In this paper, we propose a Multi-Strata Space Time Code(MSSTC) for MIMO retransmissions. Since MSSTC is constructed by superimposing two OSTBC matrices, there are no intra-stratum interferences, but there exist inter-strata interferences. In MIMO retransmission environment, the transmitter switches adaptively the phases of strata at each transmission by using 1-bit feedback sent from the receiver in order to reduce the inter-strata interferences efficiently. We also propose a power allocation scheme between strata to improve error performance. Simulation results show that the proposed scheme achieves better performance than other conventional schemes.
