<p>Provided are a correction method for channels, and a mutual correction method, device and system for channels. The correction method for channels comprises: conducting downlink digitization processing on a correction sequence received from an RRU; sending the sequence after the downlink digitization processing to a BBU, so as to enable the BBU to calculate correction coefficients corresponding to all sending channels of the RRU based on a predetermined sending channel reference sequence according to the sequence after downlink digitization processing; conducting uplink digitization processing on the correction sequence received from the BBU; and sending the sequence after the uplink digitization processing to the RRU, so as to enable the RRU to return the received sequence after the uplink digitization processing to the BBU, and enable the BBU to calculate correction coefficients corresponding to all receiving channels of the RRU based on a predetermined receiving channel reference sequence according to the sequence after the uplink digitization processing returned by the RRU. The embodiments of the present invention are high in channel correction accuracy.</p> |
