Abstract

本发明实施例提供一种收发共用天线的自干扰消除方法、收发机和通信设备，包括：在自干扰信道测量时隙内，在发射通道上发送第一参考信号，并在参考信号接收通道上接收第二参考信号，第二参考信号为第一参考信号经过自干扰信号传输通道后的参考信号；根据第一参考信号和第二参考信号进行信道估计，得到自干扰传输通道的描述信息；在数据收发时隙内，在发射通道上发送第一通信信号，并在通信信号接收通道上接收第二通信信号，第一通信信号为从所述收发共用天线发射的信号，第二通信信号为从收发共用天线接收的信号；根据第一通信信号和自干扰传输通道的描述信息，得到自干扰信号，并采用该自干扰信号对第二通信信号进行自干扰消除。
