摘　　要：构建了一种四元数正交设计的极化空时分组码(orthogonal space time polarization block code,OSTPBC),该码满足正交设计关系,能够通过极化天线进行发射和接收,并且可以进行满码率发射.在速率和传输速率相同的情况下,对正交极化空时分组码和发射天线数为4的复正交设计空时分组码进行仿真比较,结果表明正交极化空时分组码在不增加发射天线和接收天线的情况下可以有效降低误码率,提高系统性能.A new kind of space time block code based on quaternion orthogonal design is introduced. The new code can be transmitted through dual-polarized antennas and received through dual-polarized antennas, and can provide full transmission rate. In the case of same rate and same transmission rate, compared with the space time block code of 4 transmit antennas from complex orthogonal design, the simulation results show that OSTPBC from quaternion orthogonal design can reduce the bit error rate and improve the performance of system.
