    摘要： It is possible to intuitively determine whether to control transmission power of a current data transmission rate mode or to change the data transmission rate mode by extracting an automatic gain controller (AGC) index after driving algorithm of an AGC, recognizing a channel clear assessment (CCA) status by using the extracted AGC index, and generating link quality indicator (LQI) information to be transmitted from a physical layer to a media access control (MAC) layer by using the AGC index, when the CCA status is high, in order to embody effective piconets in a multi-band orthogonal frequency division multiplexing ultra-wide band system (MB-OFDM UWB system) including a receiver having a dynamic gain controller(DGC) and the AGC.

    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.
