Constellation rotation is used to the input symbol vector to ensure full diversity, and then the information symbol vector is interleaved in coordinates and pre-grouped by using a Given rotation matrix. The performance is evaluated by numerical experiments. The PAPR of our proposed QOSTBC is lower than that of CI-QOSTBC in Khan and Rajan (IEEE Trans Inf Theory 52(5):2062-2091, 2006). Meanwhile, the Bit-error-rate versus Signal-to-noise-ratio of our proposed QOSTBC is better than those of OSTBC (Tarokh etal. in IEEE Trans Inf Theory 45(5):1456-1467, 1999) QOSTBC (Jafarkhani in IEEE Trans Wirel Commun 49(1):1-4, 2001), G-QOSTBC (Park etal. in IEEE Commun Lett 12(12):868-870, 2008), slightly better that of the CI-QOSTBC, and as same as that of the recently proposed Minimum Decoding Complexity QOSTBCs (MDC-QOSTBC) in Yuen etal.(IEEE Trans Wirel Commun 4(5):2089-2098, 2005), Wang and Xia (IEEE Trans Inf Theory 55(3):1104-1130, 2009). Compared with MDC-QOSTBC, the proposed QOSTBC has simpler code construct and lower decoding complexity.
