摘　　要：随着IMT-Advanced标准化进程的展开,TDD技术的研究成为利用和延续我国已有技术TD-SCDMA、TD-LTE的重要手段之一。本文在利用TDD信道互易性的基础上,针对现有LTE帧结构2,提出了基于MMSE(最小均方误差)的线性信道预测模型,同时,对在不同移动速度下单帧递推信道预测及多帧递推信道预测的性能进行了仿真和对比。With IMT-Advanced standardization process developing,research of time division dual technology has become one of important means which utilize and extend Chinese existing technologies.For long term evolution frame structure 2,paper on the basis of time division dual channel reciprocity proposes a linear channel prediction model based on minimum mean squared error.Meanwhile,it simulates and compares the performance under different speeds of single frame recursive channel prediction and multi-frame recursive channel prediction.
