多RRU间通道校正方法及装置
摘要：
本发明公开了一种多RRU间通道校正方法及装置，属于通信技术领域。所述方法包括：对所述第一RRU和所述第二RRU分别进行自校正，并分别获取第一自校正系数和第二自校正系数；通过所述第一RRU向所述第二RRU发射第一校正序列，所述第一校正序列到达所述第二RRU时变为第二校正序列；通过所述第二RRU向所述第一RRU发射所述第一校正序列，所述第一校正序列到达所述第一RRU时变为第三校正序列；将所述第一RRU接收到的所述第三校正序列发送给所述第二RRU；根据所述第二校正序列、所述第三校正序列和所述第二自校正系数获取所述第二RRU的校正系数。
摘要（英）：

The invention discloses a correcting method and device for channels between multiple RRUs, and belongs to the technical field of communications. The correcting method includes the steps that self correcting is carried out on the first RRU and the second RRU, and a first self correcting coefficient and a second self correcting coefficient are respectively obtained; a first correcting sequence is transmitted to the second RRU through the first RRU and is changed into a second correcting sequence when reaching the second RRU; a first correcting sequence is transmitted to the first RRU through the second RRU and is changed into a third correcting sequence when reaching the first RRU; the third correcting sequence received by the first RRU is sent to the second RRU; the correcting coefficient of the second RRU is obtained according to the second correcting sequence, the third correcting sequence and the second self correcting coefficient.
