1. An apparatus for ultra wideband (UWB) communication, comprising:

  • a wideband low noise amplifier (LNA) configured to remove noise included in a received UWB signal, and amplify the UWB signal from which the noise is removed;

    a first band pass filter (BPF) configured to filter the amplified UWB signal to produce a first filtered signal, the first BPF having a first center frequency;

    a second BPF configured to filter the amplified UWB signal to produce a second filtered signal, the second BPF having a second center frequency that differs from the first center frequency; and

    a demodulator configured to demodulate the UWB signal using a magnitude of the first filtered signal and a magnitude of the second filtered signal,wherein the magnitude of the first filtered signal is configured to be at a minimum at the second center frequency of the second BPF, andwherein the magnitude of the second filtered signal is configured to be at a minimum at the first center frequency of the second BPF.
