Abstract :
The Quasi-orthogonal space-time block code ensure that data transfer at full speed. However, it will reduce the error performance. Based on it, this paper proposed a new quasi-orthogonal space-time block code using full rate of the four transmit antenna. And it proposed the decoding method based on maximum likelihood algorithm. A number of simulation results demonstrate that the proposed algorithm has better error performance than the typical Jafarkhani quasi-orthogonal space-time block code.
