The conventional quasi-orthogonal space-time block code (QO-STBC) for four transmit antennas is full rate, but achieves only half of maximum achievable transmit diversity and the order of its decoding complexity is quadratic. The interference between two symbols causes the deterioration of the signal quality. In this paper, we propose a scheme which makes possible to linear decoding, and two schemes to gain full transmit diversity by upsetting the balance of the transmit power and rotating constellation. |
