    • Provided are a receiver and a receiving method for a scalable bandwidth in a mobile station of an Orthogonal Frequency Division Multiplexing (OFDM) system. The receiving method includes the steps of: (a) filtering a received RF signal; (b) oscillating a frequency according to a center frequency control signal to output a local oscillation frequency; (c) down-converting the filtered RF signal by using the local oscillation frequency; (d) scalable-filtering the down-converted signal while adjusting a bandwidth according to a bandwidth control signal; (e) controlling gain of the scalable-filtered signal; (f) converting the gain-controlled analog signal into a digital signal by using a sampling frequency matching with a corresponding bandwidth according to an ADC control signal; and (g) demodulating the converted digital signal, outputting the center frequency control signal, the bandwidth control signal, and the ADC control signal according to control information received from an upper layer.
    • 提供了一种用于正交频分复用(OFDM)系统的移动台中的可扩展带宽的接收机和接收方法。 接收方法包括以下步骤:(a)对接收到的RF信号进行滤波; (b)根据中心频率控制信号振荡频率以输出本地振荡频率; (c)使用本地振荡频率对滤波的RF信号进行下变频; (d)在根据带宽控制信号调整带宽的同时可缩放滤波下变频信号; (e)控制所述可缩放滤波信号的增益; (f)通过使用根据ADC控制信号的与相应带宽匹配的采样频率将增益控制模拟信号转换成数字信号; 和(g)根据从上层接收到的控制信息解调转换的数字信号,输出中心频率控制信号,带宽控制信号和ADC控制信号。
