Title:
SIGNAL CHANNEL CORRECTION COMPENSATION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/063497
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to wireless communication technologies, and particularly to a signal channel correction compensation method, apparatus and system. The method comprises: a baseband unit (BBU) receives received signals from correction reference channels of a remote radio unit (RRU), the received signals being signals outputted corresponding to transmission channels after the BBU sends transmission correction reference signals to the transmission channels in the RRU; the BBU determines channel delays of the transmission channels according to the received signals; the BBU determines compensation coefficients of the transmission channels by using a transmission channel corresponding to a minimum channel delay as a transmission reference channel; and the BBU performs correction compensation on the transmission channels according to the compensation coefficients of the transmission channels, the number of the received signals being a positive integer greater than 1, and the number of the received signals being equal to the number of the transmission channels. The signal channel correction compensation method, apparatus and system in the present invention can effectively reduce inter-symbol interference of received signals.
