Power estimation method, frequency spectrum characteristic monitoring method, device and system

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating power, a method for monitoring a frequency spectrum characteristic, an apparatus and a system.SOLUTION: The method for estimating power includes: obtaining a received signal; extracting frequency spectrum information from the received signal, so as to obtain a frequency spectrum of the received signal; estimating power of a central channel according to a power value in a flat area of the central channel in the frequency spectra; and estimating power of a neighboring channel according to a power value in a flat area of the neighboring channel in the frequency spectra.SELECTED DRAWING: Figure 2
