    • A method and apparatus for transmitting/receiving broadcasting-communication data is provided. The apparatus includes: an original signal generator (102) configured to receive the original data and generate baseband original signals; a first modulator (104) configured to receive the baseband additional signals and generate original signals of a predetermined band; and additional signal generator (106) configured to receive the additional data and generate baseband additional signals; a second modulator (108) configured to receive the baseband additional signals and generate additional signals of a predetermined band; an average power controller (110) configured to control an average power of the additional signals of the predetermined band; an inserter (112) configured to insert the additional signals of the predetermined band with a controlled average power to the original signals of the predetermined band to thereby generate mixed signals of a predetermined band; and a transmitter (114) configured to transmit the mixed signal of the predetermined band.
    • 提供了一种用于发送/接收广播通信数据的方法和装置。 该装置包括:原始信号发生器(102),被配置为接收原始数据并产生基带原始信号; 第一调制器(104),被配置为接收所述基带附加信号并产生预定频带的原始信号; 和附加信号发生器(106),被配置为接收附加数据并产生基带附加信号; 第二调制器(108),被配置为接收所述基带附加信号并产生预定频带的附加信号; 平均功率控制器(110),被配置为控制所述预定频带的附加信号的平均功率; 插入器(112),被配置为以预定频带的原始信号插入具有受控平均功率的预定频带的附加信号,从而产生预定频带的混合信号; 以及被配置为发送预定频带的混合信号的发射机(114)。
