Abstract: The present invention relates to a practical interference alignment method using multiple antennas in a multi-cell overlapping environment. The channel information needed to configure a signal processing filter for each transceiver node is restricted to local CSI. Moreover, each transceiver node can design its own signal processing filter using the local CSI and apply the signal processing filter in an environment where a normal number of transmission and reception pairs exist.

Abstract: PURPOSE: A data transceiver, a data transceiving antenna, a sharing method between a sensing receiver and a sensing antenna, and a wireless communication system are provided to improve the use efficiency of the transceiver and the antenna through smooth sharing of each transceiver and antenna. CONSTITUTION: In case a current time section is a data transceiving section, a data transceiver transmits and receives data(410,420). In case the time section is a QP(Quiet Period), the data transceiver receives inband sensing data with a sensing receiver(430,440). In case the time section is not the QP, a data signal processor confirms a separate sensing schedule(450). In case there is the sensing schedule, the data transceiver receives sensing data(460).

Abstract: PURPOSE: A preamble generation device, a method thereof, a preamble receiving device and a method thereof are provided to improve data transfer rate as the size of the address information by detecting transmitting and receiving address to preamble. CONSTITUTION: A shift register input unit(110) inputs at least one among the address of the source node transmitting a frame and address of the receiving node receiving a frame to a shift register. An address sequence generation unit(120) generates address sequence of subcarrier number size of the preamble of the frame in the shift register based on the output value shifted by each clock. A preamble transform unit(130) changes the produced address sequence through the IFFT into the time domain signal of preamble. The preamble transform unit transforms calculated the modular(modulo) -2 to the IFFT by adding the produced address sequence based on the received node address and the produced address sequence based on the transmission node address.

Abstract: PURPOSE: A channel sensing scheme using a natural quiet period in a cognitive radio system is provided to reduce transmission period by reducing the frequency of QP allocation through the energy detection with an NQP. CONSTITUTION: An NQP information collecting unit(401) searches, from a network having a data transmission and reception period and an idle period, the period in which data transmission is stopped. A channel searching unit(402) searches the searched period, and a channel searching information processor(403) determines the length of idle period based on the searching result. In a reservation-based mesh network, the period in which data transmission is stopped corresponds to an IFS(Inter Frame Space).
