    摘要： 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.

    摘要： 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.

    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.

    摘要： 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.
