Joint Interleaving With Transmit Diversity for Nx SCFDMA MIMO System

Nx SC-FDMA has been accepted as one of the main multiple access schemes for LTE-Advanced, which has been attracted much attention for supporting extended bandwidth. The classical transmit antenna diversity technique as Frequency Switched Transmit Diversity (FSTD) has divided the transmitted data into two sub-groups, with each group being transmitted from half sub-carriers associated with one transmit antenna, which results in the frequency diversity gain loss in frequency selective channels. In this paper, a joint interleaving with FSTD scheme is proposed for Nx SC-FDMA system.
