Title:
PILOT PROCESSING METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/028702
Kind Code:
A1
Abstract:
A pilot processing method, apparatus, and system, providing an effective way to determine pilot locations. The method comprises: a receiving end performing Fourier transform processing on an acquired electrical signal to obtain a spectrum signal; the receiving end determining the sum of an amplitude corresponding to a first frequency point and an amplitude corresponding to a second frequency point within a preset frequency range in the spectrum signal, wherein the first frequency point and the second frequency point are any two frequency points within the preset frequency range with frequencies differing by a first frequency interval, and the first frequency interval being equal to a predetermined frequency interval between two pilots in an optical signal transmitted by a transmitting end; and the receiving end locating and determining two frequency points having the highest sum within the preset frequency range as pilots. In this way, the locations of pilots can be accurately determined.
