Abstract
The present application discloses a method and an apparatus for signal processing. In the present application, since a front end device in a base station system performs MIMO detection and related baseband-processing of a time domain signal received from an antenna unit and transmits the signal that is baseband-processed to a back end device of the base station system, the back end device merely performs other baseband processing, apart from the MIMO detection and the related baseband processing. Compared with the prior art, the embodiments of the present application move some of the baseband processing forward to be implemented on a front end device such that only the data of each scheduled user with less redundancy are required to be transmitted in an interface between the front end device and a backend device, reducing the pressure on the rate of data transmission between the front end device and the back end device.
