摘要

提出了一种基于给定旋转的低误码率全速率准正交STBC正交信道矩阵的构造方案。传输分集方法旋转每一个单独的信息符号。该方案能很好地抑制信道噪声，消除干扰项。仿真结果表明，该方法在不增加译码复杂度的前提下，能较传统算法更好地提高译码性能。

A New Scheme to Construct Orthogonal Channel Matrix for MIMO STBC by Givens Rotation

This paper proposes a scheme to construct orthogonal channel matrix for full rate quasiorthogonal STBC based on givens rotation with lower bit error rate. The transmission diversity method rotates every single information symbol. The scheme can suppress channel noise and eliminate the interference term well. Simulation results show that the method can improve performance better than conventional algorithm without increasing decoding complexity.
