Abstract: A system and method for verifying the face of a user using a light mask are provided. The system includes a facial feature extraction unit for extracting a facial feature vector from a facial image received from a camera. A non-user Gaussian Mixture Model (GMM) configuration unit generates a non-user GMM from a facial image stored in a non-user database (DB). A user GMM configuration unit generates a user GMM by applying light masks to a facial image stored in a user DB. A log-likelihood value calculation unit inputs the facial feature vector both to the non-user GMM and to the user GMM, thus calculating log-likelihood values. A user verification unit compares the calculated log-likelihood values with a predetermined threshold, thus verifying whether the received facial image is a facial image of the user.

A base station receives a first signal in a first time interval from a first mobile station which is at least one mobile station located in a third region which is a region where a first region which is a region of the base station itself overlaps with a second region which is a region of a relay station. The relay station receives a second signal in the first time interval from a second mobile station which is at least one mobile station located in a fourth region which is a region not overlapping with the first region in the second region, and receives the first signal from the first mobile station. The relay station transmits a third signal including the first signal and the second signal to the base station in a second time interval.

Abstract: A word line driving circuit includes a read voltage generator and a word line driver. The read voltage generator precharges a clamp capacitor with a power supply voltage to stably generate a read voltage in response to a read command. A capacitance of the clamp capacitor is varied to compensate for a fluctuation of a power supply voltage level. The word line driver distributes electric charges precharged in the clamp capacitor to a word line in response to a word line selecting signal. Therefore, the word line driving circuit reduces unnecessary power consumption in a standby mode by operating the word line rapidly with charge sharing in a read mode.

Abstract: Radio resource allocation apparatus and method in a multi-channel system are provided. The method includes determining a type of a channel to be allocated to terminals, which request a resource allocation. When there is a terminal to be assigned the band AMC channel, necessary resources are allocated to the terminal as resources of the band AMC channel within a frequency band preferred by the terminal. A virtual resource space is generated which collects resources not allocated as the resources of the band AMC channel. Resources are allocated to terminals to be assigned the diversity channel from within the virtual resource space. Accordingly, the radio resources can be efficiently allocated in the multi-channel system where the diversity channel and the band AMC channel coexist.
