提出了一种新的差分酉空时码，它是不同阶群对角矩阵与酉范德蒙矩阵的乘积。通过对所提出的码的块错误概率的联合界的性质，设计被简化。通过对角矩阵的性质，形成一个循环组，检测简化。示出了优于最佳已知差分空时码的上级性能，特别是对于3、5和6个发射天线。
A new differential unitary space-time code is presented that is a product of group diagonal matrices of different orders and a unitary Vandermonde matrix. Design is simplified through properties of the union bound on block error probability for the presented code. Detection is simplified via properties of the diagonal matrices which form a cyclic group. Superior performance to best known differential space-time codes is shown, particularly for 3, 5 and 6 transmit antennas.
