In the multi-hop communication method based on distributed medium access control according to the present invention, a beacon frame which includes a first multi-hop information element is generated and transmitted to a neighboring device so as to search for a route to an external device which does not belong to a beacon group. A third multi-hop information element, which is generated based on a second multi-hop information element generated by the external device, is received from the neighboring device. A multi-hop route to the external device is set up in accordance with the third multi-hop information element, and data is transmitted to the external device. Therefore, a multi-hop route between devices in the extended beacon group can be efficiently set up.

摘要： Provided is a method for adjusting Fast Fourier Transform (FFT) window positioning in a Multi Band Orthogonal Frequency Division Multiplexing Ultra-Wideband (MB-OFDM UWB) system. The method includes the steps of acquiring an initial FFT window position and a frequency hopping position, demodulating a received signal by using the initial FFT window position and the frequency hopping position acquired in the acquiring step, transmitting received data information to a Media Access Control (MAC) layer with a reception frame (RX frame) structure and judging at the MAC layer whether or not a packet error is occurred based on Frame Check Sequences (FCSs), and if no packet error is occurred, returning to the demodulating step, and if the packet error is occurred, changing a register map by using a predetermined interface line in a MAC-physical layer (MAC-PHY) interface to thereby adjust the FFT window position and the frequency hopping position, and then returning to the demodulating step.
