Title:
CHANNEL CORRECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/152732
Kind Code:
A1
Abstract:
The present application discloses a channel correction method and device, relating to the field of communication technology. The invention is invented to solve the problem existing in the prior art that in an application scenario of low signal to noise ratio, an accurate correction coefficient cannot be obtained, and thereby channel estimation cannot be realized accurately. The method comprises: obtaining a first channel estimation result and a second channel estimation result; determining a first time domain position on the basis of the first channel estimation result, and determining a second time domain position on the basis of the first time domain position; performing noise reduction on the first channel estimation result according to the first time domain position and a preset filter window function to obtain a first target channel estimation result; performing noise reduction on the second channel estimation result according to the second time domain position and the preset filter window function to obtain a second target channel estimation result; and determining a correction coefficient on the basis of the first target channel estimation result and the second target channel estimation result. This application is applied to the process of channel correction between different RRUs.
