摘要

研究了空时编码中存在信道估计误差时星座旋转方案的性能。给出了考虑星座旋转的最优组合方程。仿真结果表明，在变信噪比条件下，星座旋转在信道估计误差方差较小的情况下具有较好的误码率性能。

An enhanced transmitter diversity scheme with constellation rotation to estimation errors

The performance of constellation rotation scheme in the presence of channel estimation error for space-time coding is investigated. The optimal combining equations with constellation rotation are presented. The simulation results show that the constellation rotation provides the better BER performance in a low variance of channel estimation error for varying signal-to-noise ratio (SNR).
