摘要
提出了OFDM通信系统中一种新型自适应信道估计方法。利用信道冲激响应的最重要分量,该自适应信道估计方法能有效降低子载波间干扰和高斯白噪声的影响。根据性能仿真结果比较,本方法的MSE和BER结果优于变换域插值、时域插值。
A novel adaptive channel estimation method for OFDM communication system is proposed. This method can effectively suppress the influence of inter-carrier interference and white Gaussian noise by the uppermost component of shock response. Based on the comparison of simulation result, the MSE and BER of feedback DFT-based interpolation are lower than the resuh of time domain interpolation and transform domain interpolation.
