Abstract

本发明的目的是提供一种对天线阵列进行盲校准的方法和装置；自天线阵列的多路输入通道中选择一路作为参考通道，计算该参考通道的射频响应；根据该射频响应，以及多路输入通道中除该参考通道以外的任意一路输入通道的输入信号，确定该任意一路输入通道的输入信号经由重构参考通道的仿真输出信号；再结合经由所述任意一路输入通道传输后的实际输出信号，计算对该任意一路输入通道的校准滤波器系数，并据此校准该任意一路输入通道。与现有技术相比，本发明利用参考通道的频响重构不同时刻的参考通道，并与当时的输出进行比较，从而得到补偿滤波器，实现对上下行天线阵列的校准，由于不需要参考符号，没有吞吐量的损失，并且可以和标准兼容。
