Ultra wide band device for detection and avoidance of ultra wide band signal

摘要

Example embodiments are directed to a method for detection and avoidance (DAA) of an ultra wide band (UWB) signal and a UWB terminal. The method includes: shifting a data signal by a desired frequency in a first direction; filtering the shifted data signal through a notch filter; and shifting the filtered data signal by the desired frequency in a second direction, the second direction being opposite to the first direction. The UWB terminal comprises an encoder for encoding data signals; a tone nulling unit for changing at least one tone of the plurality of tones into a null tone; an inverted fast Fourier transformer; a low pass filter for filtering the inverted fast Fourier transformed data signals; a filter circuit for attenuating an intensity of the low pass filtered signal; and a radio frequency (RF) circuit for transmitting the filtered signal.
