| 摘 要： | 针对频率选择性块衰落MIMO信道，该文提出一种改进的基于参数信道模型的信道估计方法。该方法首先通过修正后的TST-MUSIC算法估计多径的传播时延和角度。由时延和角度信息，得到一种基于参数信道模型的信道估计方法。仿真结果表明此种方法可以有效地减少参数估计的维数，其性能要远远优于非参数的最小二乘估计器。

| Abstract: | An improved channel estimation scheme based on estimation of parameters is presented for frequency-selective MIMO channels. In the algorithm, the propagation delays and the angles of multipath are firstly estimated by a modified TST-MUSIC algorithm. With the information of multipath delays and angles, an estimator based on parametric channel model is derived and the estimator’s performance is analysed. Simulation results show that the method can effectively decrease the dimension of estimated parameters, consequently has much better performance than the nonparametric least square estimator. |
