專利摘要：
An apparatus and a method of defining symbol timing window and capturing signal axe provided for a UWB receiver (200). The present invention is characterized in delaying a start point of a symbol timing window for a preset time T. According to the symbol timing window, serial symbol signals are received and each of received symbol signals comprises a prefix signal (PS), a received data signal (RS), and a guard signal (GS). The time period of the prefix signal is T1-T, the time period of the guard signal is T2+T, and T & T1-T2. In addition, the received data signal and the guard signal are captured, and then the guard signal is added to the front of the received data signal. The overall duration of the received signal is unchanged. The method compensates for channel effects in the received signal.
