超宽带系统中一种改进的信道估计方法
n improved channel estimation method for UWB system
文章研究了UWB中的信道估计问题。首先讨论了UWB中的LS和DFT信道估计算法，在此基础上提出一种新的基于UWB信道特性的信道估计方法。和前两种方法比较，新方法能够根据信道的不同特性自适应选择合适的时域滤波器长度，因此有比较低的误码率。基于IEEE中标准信道CM1和CM2的仿真结果验证了新结果的正确性。
UWB channel estimation problem is considered. Two channel estimation methods based on LS and DFT for UWB system are respectively discussed, a novel channel estimation method based on the former results are proposed. As it can adaptively track the time domain filter length, the new method has the lower Bit error rate. Computer simulation results based on two standard IEEE CM1 and CM2 channels verify our analysis.
