摘要
在分析信道传输函数频谱特性的基础上,提出了一种改进的变换域信道估计方法,该方法通过改进低通滤波器的传输函数,有效地减小了符号间干扰和加性高斯白噪声对信道估计精确度的影响。仿真结果证明,在多普勒频移较大的情况下,该方法仍具有较小的误码率。
Based on the characteristics of channel function, a new improved transform domain channel estimation method is presented in this paper. This method reduces ICI and AWGN in the receiving signal effectively by improving the low pass filter. Simulation proves that this method could provide better perfortnance.
