一种适用于连续衰落信道的非对角差分空时调制方法被提出,该方法在线性预测的基础上,通过采用判定反馈检测技术,不仅解决了对角阵DSTM的性能衰减问题,而且通过在多符号差分矩阵中插入判定反馈符号,解决了非对角DSTM的性能衰减问题,同时降低了计算复杂度。仿真结果表明,这种新机制有效改善了DSTM的性能,适用于对角阵星座图,同时也适用于非对角阵星座图。 A non-diagonal differential space-time modulation method suitable for continuous fading channels is proposed. Based on the linear prediction, the proposed method not only solves the problem of performance degradation of diagonal array DSTM, The decision feedback symbol is inserted into the multi-symbol differential matrix, which solves the performance degradation of non-diagonal DSTM and reduces the computational complexity. The simulation results show that this new mechanism can effectively improve the performance of DSTM. It is suitable for diagonal constellation and also for non-diagonal constellation.
