    • Provided are an apparatus and method for transmitting multi-carriers to provide a high-quality service to multicast-based service subscriber terminals. The method includes: mapping first data for providing the multicast service, and second data different from the first data, to s different antennas; converting the first mapped data into a first Intermediate Frequency (IF) signal and the second mapped data into a second IF signal; converting the first IF signal into a first RF signal having a carrier frequency, and deciding a power intensity of the first RF signal so that the first RF signal is transmitted over the entire coverage region of the base station; and converting the second IF signal into a second RF signal having the other carrier frequency, and to deciding a power intensity of the second RF signal so that the second RF signal is transmitted over a predetermined region around the base station.
    • 提供了一种用于发送多载波以向基于多播的服务用户终端提供高质量服务的装置和方法。 该方法包括:将用于提供多播服务的第一数据和与第一数据不同的第二数据映射到不同的天线; 将第一映射数据转换成第一中频(IF)信号,将第二映射数据转换成第二IF信号; 将所述第一IF信号转换为具有载波频率的第一RF信号,并且确定所述第一RF信号的功率强度,使得所述第一RF信号在所述基站的整个覆盖区域上传输; 以及将所述第二IF信号转换为具有所述另一个载波频率的第二RF信号,并且确定所述第二RF信号的功率强度,使得所述第二RF信号在所述基站周围的预定区域上传输。
