一种抗多普勒效应的改进自适应信道估计算法*

提出了一种抗多普勒效应的改进自适应信道估计算法，该算法通过递归地更新信道估计值和应用矩阵求逆法来降低计算的复杂度以及应用直接判决（DD）法对信道进行估计和跟踪。仿真结果表明，本算法在降低计算复杂度和没有影响系统误码性能的情况下，在快衰落环境中对高多普勒频移有一定的鲁棒性。

Efficient adaptive channel estimation algorithm for Doppler effect elimination

This paper proposed an efficient adaptive channel estimation algorithm for Doppler effect elimiantion.recursively the computational complexity by recursively updating the channel estimates and by applying the matrix inversion lemma, the estimator was to perform DD channel tracking.The results from simulation demonstrate that the new algorithm improve the BER performance and exhibits robust performance in fast fading environments with high Doppler frequencies.
