摘　　要：从提升空域信道差异角度出发,提出一种空时跳变去信道相关性的方法。该方法在不同子信道上叠加不同的动态变化的"人工信道",通过提升子信道差异达到去信道相关的目的。仿真结果表明,在收发相关矩阵相关系数和信噪比为16d B时,结合注水功率分配方案,文章方法可提升MIMO信道容量1.4倍。From the perspective of increasing spatial channel difference, a novel space-time hopping method to reduce channel correlation is proposed. By superposing different dynamic change of ＂arti-ficial channel＂ on different channels, channel differences are increased and their correlations are lowered. Combined with equal power allocation and water power allocation, the simulation results show the proposed method can effectively improve MIMO system capacity.
