Abstract:
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, and wherein the magnitude of the second filtered signal is configured to be at a minimum at the first center frequency of the second BPF.
