Title:
SIGNAL PROCESSING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/197324
Kind Code:
A1
Abstract:
Provided is a signal processing method, comprising: dividing a frequency band for sending a downlink synchronization symbol into at least two parts of non-overlapping frequency bands, the two parts of frequency bands being a first frequency band and a second frequency band; allocating frequency points on the first frequency band and the second frequency band to a sounding sub-carrier and a markup sub-carrier, so that the sounding sub-carrier and the markup sub-carrier distributed on the second frequency band are respectively symmetric with the sounding sub-carrier and the markup sub-carrier distributed on the first frequency band based on a symmetry point, the symmetry point being the lowest frequency point of the second frequency band, the highest frequency point of the first frequency band or one frequency point between the lowest frequency point of the second frequency band and the highest frequency point of the first frequency band; and modulating a downlink pilot frequency sequence onto the sounding sub-carrier on the first frequency band and the second frequency band and then sending same to an opposite-end device. Also provided are a signal processing apparatus and a network system.
