摘　　要：提出利用有限新息率采样理论解决超宽带信道估计问题,建立了可用于超宽带信道估计的框架,此框架的抽样率低于奈奎斯特速率。通过实例展示了利用奈奎斯特速率抽样而工作在低于奈奎斯特抽样率的算法性能,减少了功耗,也降低了硬件的复杂性。Considering the problem of UWB channel estimation by using recently developed theory sampling the signals with finite rate of innovation. A framework for UWB channel estimation,which can work lower than Nyquist sampling rate is constructed. In certain case,the performance exceeding that of algorithm using Nyquist rate sampling while working at lower sampling rate is demonstrated, and the results show that it can save power and complexity of the hardware.
