摘 要: 基于矩阵旋转技术改进STBC,通过对非正交空时分组码信道相关矩阵采用矩阵旋转的方法,在矩阵旋转的基础上,将角度反馈引入到准正交编码中,提出了一种可以获得较高传输速率,并进一步降低误码率的编码方法。仿真证明这种简单的改进可以有效解决非正交空时分组码信道相关矩阵中存在自干扰项的问题,使系统性能得到明显提高。 In the paper, STBC is implored based on matrix rotation. The non-orthogonal space-time block code channel correlation matrix is processed by matrix rotation, and angle feedback is brought in the quasi-orthogonal. The imploved code can achieve high-rate transmission and reduce error probabilities. Simulation results demonstrate that the simple implovement can solve the problem that there is self-intereference in non- orthogonal space-time block code channel correlation matrix. Meanwhile, the system performance is implored.
