    摘要： 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.

    摘要： A piece of user equipment (UE), which has received more than two synchronization codes at the same time, has a problem in that the UE may not confirm the synchronization codes due to an increase in inter-signal interference. As a result, the UE may not acquire a primary scrambling code (PSC). A method of transmitting a forward synchronization signal in a wireless communication system includes: each base station existing in a wireless communication system generating a frame according to a predetermined unit of frame timing by using a same external clock signal; and allocating different offsets to frames of adjacent base stations by using the external clock signal so that forward link common channels included in the frames do not overlap each other, and transmitting the frames. In addition, a method of allocating a cell code suitable for an OFDM cellular system, a forward link frame transmitting method, a method of setting timing between cells, and a method of setting timing between a base station and a mobile station can be derived.
