This paper introduced a new kind of triple-polarization orthogonal space-time-polarization block code (TP-OSTP-BC) based on quaternion orthogonal designs. The new code could be transmitted through triple-polarized antennas and received through triple-polarized antennas. In the case of same rate and same transmission rate, compared with the Alamouti space-time block code and dual-polarization orthogonal space-time-polarization block code of same transmit and receive antennas , the simulation results show that TP-OSTPBC from quaternion orthogonal design can reduce the bit error rate and improve the performance of system.%构建了一种四元数正交设计的三极化正交空时极分组码,该码满足正交设计关系,能够通过三极化天线进行发射和接收.在相同的系统条件下,对相同天线数的Alamouti码和双极化正交空时极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空间体积和发射天线及接收天线数的情况下,可以有效降低误码率,提高系统性能.
