    Abstract: The present invention relates to a transmission apparatus and a corresponding transmission method for transmitting data within a multi-carrier transmission system comprising two or more transmission apparatuses that are configured to transmit the same data. To avoid destructive interferences a transmission apparatus (10) is proposed comprising a signal input (30) configured to receive multi-carrier signals (S(k)) carrying data to be transmitted, a distortion unit (32) configured to distort said multi-carrier signals (S(k)) by use of a distortion function (P(k)) including a phase parameter for differently modulating the phase of said multi-carrier signals (S(k)), wherein said distortion function (P(k)) is different from distortion functions used by other transmission apparatuses, whose coverage areas overlap with the coverage area of the present transmission apparatus, by using a phase parameter that is different from the phase parameter used by said other transmission apparatuses, and a transmission unit (34) configured to transmit said distorted multi-carrier signals as transmission signal (Tx(k)).

    Abstract translation: 本发明涉及一种在多载波传输系统内发送数据的发送装置和相应的发送方法,该多载波传输系统包括被配置为发送相同数据的两个或多个发送装置。 为了避免破坏性干扰,提出了一种发送装置(10),其包括被配置为接收承载要发送的数据的多载波信号(S(k))的信号输入(30),失真单元(32) 使用包括用于不同地调制所述多载波信号(S(k))的相位的相位参数的失真函数(P(k))的载波信号(S(k)),其中所述失真函数 ))不同于其覆盖区域与本发送装置的覆盖区域重叠的其他发送装置使用的失真函数,通过使用与所述其他发送装置使用的相位参数不同的相位参数,以及发送单元 (34),被配置为发送所述失真的多载波信号作为发送信号(Tx(k))。
