Abstract

The major drawback of the orthogonal space time codes (OSTC) is the limited rate achieved by this family of codes. The known answer to this problem is the quasi-orthogonal space time codes (QSTC) which enables full rate with the penalty of high complexity decoding. Both degrades the performance of a system with high data rate demand due to the use of large constellation size to compensate the low symbol rate for the OSTC and the use of non-optimal but tractable decoding scheme for the QSTC. In this paper we present a way to increase the OSTC code rate while maintaining its orthogonal property which results in low complex decoding and improved performance for high data rate systems. © 2008 IEEE.
