Claim Text:
1. A method for correcting a receiving and sending channel response, applied in a communication system comprising at least two coordinated radio frequency modules, wherein the at least two coordinated radio frequency modules comprise a first radio frequency module covering a first cell and a second radio frequency module covering a second cell, the first radio frequency module is connected to a first baseband module, the second radio frequency module is connected to a second baseband module, the first radio frequency module comprises at least a first receiving and sending channel corresponding to a first antenna, the first receiving and sending channel comprises a first sending channel and a first receiving channel, the second radio frequency module comprises at least a second receiving and sending channel corresponding to a second antenna, and the second receiving and sending channel comprises a second sending channel and a second receiving channel, and the method comprises: taking, by the first radio frequency module, the first receiving and sending channel as a reference correction channel in the first radio frequency module, correcting a channel response ratio of each receiving and sending channel in the first radio frequency module, so that the channel response ratio of each receiving and sending channel in the first radio frequency module is consistent with a channel response ratio of the first receiving and sending channel; and taking, by the first radio frequency module, the first receiving and sending channel and the second receiving and sending channel as correction channels of the first radio frequency module and the second radio frequency module, correcting a channel response ratio of the second receiving and sending channel, so that the channel response ratio of the second receiving and sending channel is consistent with the channel response ratio of the first receiving and sending channel.
