Abstract
The present disclosure relates to a remote radio unit (RRU), which is connected to a baseband unit (BBU) and an antenna, comprising: a service transmit channel configured to transmit a first correction signal through the antenna, and a standing wave detecting circuit associated with the service transmit channel, wherein: a working frequency of the standing wave detecting circuit is consistent with the service transmit channel, and the standing wave detecting circuit is capable of detecting a standing wave ratio of the service transmit channel and is configured to receive a correction signal looped back by the antenna, and send the correction signal looped back by the antenna to the BBU, wherein the correction signal looped back by the antenna comprises a portion of the first correction signal reflected by the antenna and is used for a calculation of a correction coefficient of the service transmit channel.
