中文说明：迫零波束形成 （采埃孚-BF） 是空间信号处理技术在多个天线的无线设备。对于下行链路中，采埃孚 BF 算法允许发射机将数据发送到所需用户与零方向为不受欢迎的用户和上行链路，采埃孚 BF 收到所需的用户，以及从干扰用户方向归零。在接收模式下干扰用户的概念是理论上双不希望用户在传输模式下的信息。
English Description：
Zero-forcing Beamforming (ZF-BF) is a spatial signal processing in multiple antenna wireless devices. For downlink, the ZF-BF algorithm allows a transmitter to send data to desired users together with nulling out the directions to undesired users and for uplink, ZF-BF receives from the desired users together with nulling out the directions from the interference users.The concept of interference users in the receive mode is information theoretically dual to undesired users in the transmit mode.
