摘要： A digital phase-locked loop apparatus using FSK includes a PFD detecting phase differences between a reference clock and a frequency-divided signal, and a first adder for generating first digital control codes by adding first digital codes, second digital codes, and channel frequency codes including channel information to each other, the first digital codes being converted from time differences between first and second pulses. The apparatus further includes a digital filter correcting errors of the first digital control codes to generate second digital control codes, a DCO for varying an oscillating frequency in accordance with a digital tuning word based on the second digital control codes, and a dual modulus division unit dividing the oscillating frequency into a frequency-divided signal.

摘要： To detect a victim signal in an ultra wideband communication system, fast Fourier transform of a received signal including a plurality of time symbols is performed to generate a signal including a plurality of frequency symbols, it is determined whether a first signal is present in a first region of the signal, and if a first signal is present, the first signal is detected as a first victim signal. Next, an error signal is generated based on the signal including the plurality of frequency symbols, it is determined whether a second signal is present in a second region of the error signal, and if a second signal is present, the second signal is detected as a second victim signal.
