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.

摘要： Disclosed is a method for compensating for a specific frequency band taking an individual auditory characteristic into consideration. The method comprises receiving a signal for selecting a mode for shifting a frequency of a received voice signal to an audible frequency; and applying a control signal to a compensation filter according to the selected mode to cause the compensation filter to shift an inaudible frequency of the received voice signal to an audible frequency. The apparatus for controlling a frequency band comprises a controller and a compensation filter.
