SIGNAL PROCESSING METHOD, APPARATUS AND SYSTEM

摘要

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 to a sounding sub-carrier and a mark-up sub-carrier at intervals; allocating all the frequency points on the second frequency band to the sounding sub-carrier; 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.
