Abstract

本发明提供了一种通信技术领域中通道校准方法，该方法包括：将当前一路发射通道延时后的下行业务信号与所述发射通道的反馈信号进行滑动相关处理，采样得到所述发射通道在滑动窗口内一组相关值；所述滑动窗口为采样所述相关值的时间窗口；确定所述滑动窗口内所述一组相关值的幅度值中峰值幅度值以及所述峰值幅度值对应的点的左右相邻两点的幅度值；将所述峰值幅度值与所述左右相邻两点的幅度值进行插值运算，得到所述发射通道在滑动窗口内一组相关值的实际峰值点的幅度值、时延及相位；根据所述实际峰值点的幅度值、时延及相位进行所述发射通道的校准。本发明实施例还提供一种通道校准装置及多天线波束成型系统。本发明在通道校准过程中不需发射探测信号，避免了探测信号对业务信号的干扰。
