    • A system and methods for cancelling spatial interference associated with an original multi-carrier signal carrying at least one data transmission sent by a transmitter to an antenna array comprising a plurality of antennae and having a receiver operatively associated therewith, the system receiving a plurality of received signals respectively including interference and the original signal as received by a respective individual antenna from among the plurality of antennae, the system comprising a spatial nulling device for generating a cleaner signal by reducing at least one spatial component of the interference; and a signal manipulator operative to manipulate a derivative of the received signal so as to cause the at least one data transmission to be more concentrated in a subset of frequency bands in which the spatial nulling device is more effective and to be less concentrated in frequency bands which do not belong to the subset of frequency bands.
    • 一种用于消除与原始多载波信号相关联的空间干扰的系统和方法,所述原始多载波信号承载由发射机发送到包括多个天线并且具有与其可操作地相关联的接收机的天线阵列的至少一个数据传输,所述系统接收多个接收到的 分别包括由多个天线中的相应单独天线接收的干扰和原始信号的信号,该系统包括用于通过减少干扰的至少一个空间分量来产生更清洁信号的空间零位装置; 以及信号操纵器,其操作以操纵所述接收信号的导数,以便使所述至少一个数据传输更集中在所述空间零位设备更有效并且不太集中在频带中的频带的子集中 其不属于频带子集。
