    摘要： The present invention relates to a wired/wireless broadcasting distribution apparatus having a home broadcasting distribution function and a broadcasting channel formation/termination method using the same. A wired/wireless broadcasting distribution apparatus according the present invention receives HD-grade multi-channel ground wave/satellite/cable broadcasting signals, and converts the received broadcasting signals into an IEEE1394 Isochronous packet or converts the IEEE1394 Isochronous packet into a UWB wireless signal, and transmits the IEEE1394 Isochronous packet or the UWB wireless signal to a home client, thereby making it possible to distribute HD-grade multi-channel wired/wireless broadcasting signals requiring a transmission bandwidth of hundreds Mbps to home clients irrespective of place.

    摘要： A method for allocating distributed Medium Access Control (MAC) resources in a Wireless Personal Area Network (WPAN) includes calculating an acknowledgement overhead; calculating a Medium Access Slot (MAS) overhead depending on a payload length of a frame; calculating a transfer rate; calculating a number of frame bits to be transmitted; and calculating a first number of MASs. Thereby, the method optimized a final number of MASs required per superframe. Further, a distributed MAC resource allocation apparatus includes a MAC client for determining a resource allocation scheme and an amount of resources, and for sending a request to a MAC resource management unit; a MAC physical layer for providing a received power level or the like to the MAC resource management unit; and the MAC resource management unit for determining a payload length or the like and for allocating wireless resources to devices connected to the WPAN.

    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.
