摘要:
An apparatus for removing a DC offset during frequency direct conversion in a reception device of a wireless communication system. In the apparatus, an adder receives a digital baseband signal comprising a DC component, receives an estimated DC offset value, and calculates a difference between the digital baseband signal with the DC component and the estimated DC offset value. A DC offset calculator receives gain mode information of an analog element of the reception device, and calculates the estimated DC offset value according to the gain mode.

An AGC apparatus and method in a BWA communication system are provided, in which a MAP interpreter detects a beamformed symbol period in an (n−1)th signal, a symbol power calculator measures an average signal level of a symbol in an nth signal, and a beamforming gain calculator calculates a beamforming gain of the nth signal by adding a beamforming gain of the (n−1)th signal to a power difference between a signal of a beamformed symbol period and a signal of a non-beamformed symbol period in the nth signal using information about the beamformed symbol period of the (n−1)th signal and the average signal level of the symbol in the nth signal.

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.

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.

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.

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.
