ABSTRACT:
A method for demodulating an ultra-wide band (UWB) signal includes detecting a detecting a data rate of the UWB signal, selecting one from plurality of clock signals in response to the detected data rate, decoding the UWB signal in accordance with the selected clock signal, and outputting transmission data determined by a fast clock. The plurality of clock signals includes at least one frequency different from other frequencies. A receiver for an UWB signal includes an OFDM demodulating unit demodulating the UWB signal into an OFDM symbol, and a bit-level processing unit demodulating the OFDM symbol into bit-level data. The bit-level processing unit receives a scaled clock signal having a frequency corresponding to one of a plurality of data rates of the UWB signal. The method and apparatus may reduce static power consumption and improve performance of the receiver.
