摘要 本论文从实现的角度对LTE系统信道估计算法进行了研究,对LS、MMSE等常用的信道估计算法进行了分析和MATLAB仿真;详细介绍了采用数字化后的MMSE算法实现的信道估计器电路结构,依照3GPP物理层标准,实现了基于FPGA的TD-LTE系统上行的信道估计算法电路。仿真结果表明,所提出的数字化MMSE算法模型系统在系统复杂度和信道估计效果上都较为优化。 From the point of view of implementation, channel estimation of LTE uplink is studied in the paper. Firstly, LS, MMSE and other commonly used channel estimation algorithm are analyzed and simulated by MATLAB. Secondly, channel estimator circuit structure adopting digital MMSE algorithm is described in detail. Then, in accordance with the 3GPP physical layer standards, based on FPGA, digital channel estimation algorithm of TD-LTE uplink system is implemented. The simulation results illustrate that the digital MMSE algorithm model system is optimal in both the complexity of the system and channel estimation effect.
