High rate space-time block coded scheme: performance and improvement in correlated fading channels

In this paper, we study the performance of space-time block coding, also known as space-time transmit diversity (STTD) scheme for high data rate applications with 4 transmit antennas. The scheme consists of two STTD units at the transmitter and an interference-resistant detector at the receiver, ter...

Summary:In this paper, we study the performance of space-time block coding, also known as space-time transmit diversity (STTD) scheme for high data rate applications with 4 transmit antennas. The scheme consists of two STTD units at the transmitter and an interference-resistant detector at the receiver, termed the double-STTD (DSTTD) scheme. We compare the performance of DSTTD to general multi-input multi-output (GMIMO) signaling for a given data rate and under different channel correlation profiles. It is demonstrated that DSTTD outperforms GMIMO in all cases. In addition, additional performance gain can be attained for DSTTD in correlated channels by selectively ordering the transmit antennas to minimize the average interference terms.
