1. A method for calibrating data transmitted by coordinated Access Points (APs), comprising:

  • a base station obtaining an uplink channel frequency-domain response and a downlink channel frequency-domain response between a first AP and a second AP which participate in coordination;

    the base station dividing the uplink channel frequency-domain response by the downlink channel frequency-domain response to obtain an uplink-downlink channel response difference between the first AP and the second AP; and

    the base station calibrating the data transmitted by the first AP and the second AP in coordination according to the uplink-downlink channel response difference.
