Abstract
A method and apparatus for estimating Direct Current (DC) interference, a storage medium and a terminal are provided. The method includes: performing an accumulative adding calculation on frequency-domain modulation symbols on a corresponding frequency point of DC interference to obtain a real-time accumulated value; updating a historical accumulated value using the real-time accumulated value based on that a number of times of accumulation reaches a first preset number; or calculating a real-time accumulated average value and a long-term accumulated average value based on the real-time accumulated value and a number of times of accumulation, every time a second preset number of frequency-domain modulation symbols are accumulated, wherein the second preset number is smaller than the first preset number; and calculating a DC interference estimated value based on the long-term accumulated average value or an updated historical accumulated value.
