    摘要： A fingerprint recognition method and system for recognizing a fingerprint by storing local fingerprint images inputted from a fingerprint sensor and compositing the stored local fingerprint images into an effective single fingerprint image. The method includes obtaining relative sliding speed and directional information between the local fingerprint images, correcting sliding speed and directional values of the local fingerprint images using the obtained sliding speed and directional information, and compositing the local fingerprint images into the effective single fingerprint image using the corrected sliding speed and directional values.

    摘要： Provided is a transmission data frame in an orthogonal frequency division multiplexing (OFDM) burst mode transmission, and more particularly, a frequency offset estimating method and a channel equalizing method using a transmission data frame. In the transmission data frame used in the orthogonal frequency division multiplexing burst mode transmission, a length of a guard interval in a preamble area for frequency offset estimation and channel estimation varies depending on a channel environment not being limited in consideration of a size of a data symbol, and only data of ending part of the guard interval in the preamble is used to estimate frequency offset in consideration of intersymbol interference. In the frequency offset estimating method, desired frequency estimation efficiency can be satisfied with the small number of samples. Also, when channel equalization is performed, two symbols are averaged in a time area to reduce the accuracy of channel estimation due to Gaussian random noise. In a frequency area, by referring to weight placed on an adjacent subcarrier, a channel equalization coefficient is obtained to efficiently reduce Gaussian random noise.

    摘要： Preference of a home public land mobile network (HPLMN) is applied when a roaming user equipment (UE) selects a visited public land mobile network (VPLMN). The roaming UE sends an available VPLMN list to the HPLMN. A control message of a non-access stratum (NAS) or an application can be used to receive a preferred VPLMN list from the HPLMN or to send the preferred VPLMN list after the HPLMN requests that the UE should send the available VPLMN list or without a request. The HPLMN manages a VPLMN to be used by the roaming UE and enables a user to receive a better service.
