Abstract
The present invention discloses a base band processing module N+M backup method based on switch, is characterized in that: a switch unit is added between RF transceiver unit and base band processing unit, and IQ signal forwarding between base band processing modules of the base band processing unit and RF transceiver modules of the RF transceiver unit is performed by the switch unit; handing over the functions of the base band processing module in trouble to a backup base band processing module by resetting the switch unit and modifying the path of receiving and transmitting IQ signal, therefore realizing the N+M backup for base band processing module. The present invention can effectively realize the N+M backup for the base band processing module by adding a switch unit, therefore solving the technical problem of complexity and high cost for wiring and interfacing when having a large number of BBP and TRX modules.
