Abstract: A method and apparatus for suppressing vocoder noise are provided. In the method, first information and second information are received from a channel decoder, the first information indicating whether a decoded data frame has an error and the second information being a channel quality metric, error concealment voice decoding is performed on the decoded data frame if the first information indicates that no channel decoding error has been generated and the second information is smaller than a predetermined first threshold, and normal voice decoding is performed on the decoded data frame if the first information indicates that no channel decoding error has been generated and the second information is equal to or larger than the first threshold.

Abstract: Provided are antibodies specifically binding to the epidermal growth factor receptor (EGFR) which are effective for the treatment of EGFR-mediated cancers.

Abstract: Disclosed are an epitope specific to hepatitis B virus (HBV) and use thereof. The disclosed epitope is a conservative position on which mutagenesis does not occur and, therefore, a composition including an antibody to the foregoing epitope or a vaccine composition including the epitope has very low possibility of causing degradation of curing efficacy due to HBV mutation, thus being very useful for HBV treatment.

Abstract: An apparatus and a method for receiving a multiple frequency band are provided. In the method for receiving a multiple frequency band of a terminal is a mobile communication system, respective received signal strengths or respective gains are measured with respect to a signal received via at least one Radio Frequency (RF) chain. Whether multiple frequency band reception that uses a single RF chain is possible is determined using the respective received signal strengths or the respective gains. When the multiple frequency band reception that uses the single RF chain is possible, the multiple frequency band is received using the single RF chain.

Abstract: An apparatus and method for Time-Varying Cyclic Delay Diversity (TV-CDD) in a wireless communication system are provided. The method includes, if there is a signal of an antenna path to be transmitted, determining if a current time corresponds to a preamble zone within a frame and, if the current time corresponds to the preamble zone within the frame, shifting a partial antenna path signal forward compared to a reference timing and shifting a remaining partial antenna path signal equally or backward compared to the reference timing.

Abstract: An apparatus and method for canceling a Direct Current (DC) offset in a Broadband Wireless Access (BWA) communication system are provided. The method includes canceling a DC offset by performing self-calibration in a modulator/demodulator (modem), attempting initial synchronization acquisition in the modem, and if the initial synchronization acquisition succeeds, canceling a DC offset by performing DC offset trace and cancellation.

Abstract: An apparatus and method for removing a Direct Current (DC) offset at a receiving terminal in a wireless communication system are provided. In the method, a frame is divided into at least two time resource blocks. Resource allocation information is used to discriminate between at least one time resource block of a data-unmapped interval and at least one time resource block of a data-mapped interval. The DC offset is measured during the data-unmapped interval. The DC offset is compensated during the data-unmapped interval on a time resource block basis by using the measured DC offset.
