Apparatus and method for ultra wideband communication using dual band pass filter

摘要

An apparatus and method for ultra wideband (UWB) communication, using a dual band pass filter (BPF) is disclosed. The UWB communication apparatus may include a first BPF performing a first band pass filtering with respect to a UWB signal, a second BPF that has a center frequency differing from a center frequency of the first BPF, and performs a second band pass filtering with respect to the UWB signal, a first envelope detector that detects a size of a first signal filtered in the first BPF, a second envelope detector that detects a size of a second signal filtered in the second BPF, and a demodulator that demodulates a UWB signal, using the size of the first signal and the size of the second signal.

主权项

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.
