【摘要】 在讨论了一种低采样率的超宽带信道估计算法后,对该算法的性能进行了分析并给出了仿真结果,在低于Nyquist采样率的情况下同样可获得较好的信道估计效果。在低采样率情况下进行信道估计可减小接收机A/D转换的功耗,从而降低UWB系统设计的复杂度。该算法特别适合对宽带信道进行估计,特别是在精确定位、测距、定时和同步等方面可获得很好的应用。更多还原

【Abstract】 After discussing a algorithm and its computational procedures about Ultra-Wideband(UWB) channel estimation for low-sampling rate,some performance analysis and simulation results are presented.This method allows for high-resolution channel estimation and slower A/D converters using sub-Nyquist uniform sampling,leads to reduced computational and power requirements. It is particularly suitable in applications such as estimation of wideband channels,precise position location and ranging.更多还原
