    • An apparatus and a method for channel estimation in a broadband wireless communication system are provided to normalize the gain and power of a boosted signal during a channel estimation process. An apparatus for channel estimation in a broadband wireless communication system comprises the followings: a boosting confirming unit(311) for deciding a boosting factor by determining whether each area of a receiving signal is boosted or not; a boosting factor selecting unit(313) which selects the boosting factor for compensating a boosting value of a channel estimation value according to whether each area is boosted or not through control of the boosting confirming unit(311); and a multiplier which compensates the boosting value of the channel estimation value by multiplying the channel estimation value by the boosting factor.
    • 在宽带无线通信系统中提供用于信道估计的装置和方法,用于在信道估计过程期间对增强信号的增益和功率进行归一化。 一种用于在宽带无线通信系统中进行信道估计的装置,包括以下步骤:用于通过确定接收信号的每个区域是否升压来决定升压因子的升压确认单元(311) 升压因子选择单元(313),其通过控制升压确认单元(311),根据每个区域是否升压来选择用于补偿信道估计值的升压值的升压因子; 以及乘法器,通过将信道估计值乘以升压因子来补偿信道估计值的升压值。
