摘要： A method for assigning a global address to a node in an ad-hoc network is provided. A joining node to the ad-hoc network generates a local address using its MAC address. The joining node inquires of its one-hop nodes about whether they occupy a local address that is the same as the generated local address. When the joining node is informed that there are no nodes occupying the same local address, it generates a global address using the generated local address and a global prefix provided from neighbor nodes. The joining node inquires of an Internet gateway about whether the generated global address is currently used. When the joining node is informed that there are no nodes currently using the same global address, the joining node is assigned the generated global address. Further, the joining node and the Internet gateway communicate messages via a relay node using a tunneling.

摘要： Provided is a fine frequency synchronization method of a WiBro system, and particularly, a fine frequency synchronization method which measures a spread degree of a received signal of an adjacent subcarrier using orthogonality of PN sequences and thereby estimates a frequency offset, in a base station or a wireless repeater without using a GPS receiver. The fine frequency synchronization method includes: (a) performing despreading on received adjacent subcarrier sequences, using a PN sequence transmitted from a transmitting party; (b) obtaining ratios of correlative values obtained by the despreading; and (c) estimating a frequency offset on the basis of the ratio of correlative values. Accordingly, fine frequency offset estimation with relatively low complexity is possible without using a GPS receiver in a WiBro environment where interference signals of other base stations or repeaters exist.

摘要： A wafer temporary bonding method using silicon direct bonding (SDB) may include preparing a carrier wafer and a device wafer, adjusting roughness of a surface of the carrier wafer, and combining the carrier wafer and the device wafer using the SDB. Because the method uses SDB, instead of an adhesive layer, for a temporary bonding process, a module or process to generate and remove an adhesive is unnecessary. Also, a defect in a subsequent process, for example, a back-grinding process, due to irregularity of the adhesive may be prevented.
