    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: In a local wireless communication system, a reception signal including an STF (short training field) in which a plurality of patterns are repeatedly transmitted is received, the STF including a first number of STF patterns and a second number of STF patterns, the second number of STF patterns having an opposite code to that of the first number of STF patterns. In a first frequency offset estimation and correction process and a second frequency offset estimation and correction process, frequency offset estimation is performed on a plurality of STF patterns to acquire a phase error of each sample constituting the STF patterns, and the frequency of the STF patterns is corrected based on the acquired phase error. Cross correlation is performed on a predetermined number of STF patterns, among a plurality of STF patterns output subsequent to the frequency offset estimation and correction, to detect frame timing.

    摘要: A base station and a terminal for supporting a low power mode are provided. The base station transmits a first type of beacon signal for a terminal operating in a normal mode, a second type of beacon signal for a terminal operating in a low power mode, and a charging signal for a terminal in a low power mode. The terminal harvests energy from a charging signal and receives the second type of beacon signal using the harvested energy. The terminal confirms a communication request through the second type of beacon signal, enters into an active period, and communicates with the base station.

In a high rate WPAN environment including a plurality of piconets, a piconet controller (PNC), which performs a topology server function to provide the optimal route, collects link state information from the PNCs or DEVs (devices) belonging to a sub-tree that serves as a root and applies a minimum cost algorithm based on the collected link state information to calculate the optimal route for all pairs of originations and destinations existing within the sub-tree in consideration of QoS. The optimal route information is transmitted to the origination PNC via the destination PNC/DEV. During performing this, the optimal route between the pairs of originations and destinations is set.
