DYNAMIC NARROWBAND INTERFERENCE AVOIDANCE METHOD AND APPARATUS SUITABLE FOR BROADBAND OFDM SYSTEM, STORAGE MEDIUM, AND TERMINAL

摘要

Disclosed are a dynamic narrowband interference avoidance method and apparatus suitable for a broadband OFDM system, a storage medium, and a terminal. The method comprises: determining, according to parameters of a broadband OFDM system and a narrowband interference system, a range set Φ of OFDM subcarriers that may be interfered by narrowband and the number n of OFDM subcarriers that may be interfered by one single narrowband interference system; estimating noise powers of the OFDM subcarriers in the set Φ on the basis of a preset period to generate an estimated noise power value set Ω; determining whether there is narrowband interference in each subcarrier in the set Φ according to the estimated noise power value set Ω and the parameter n; and if there is narrowband interference in the subcarriers in the set Φ, actively initiating a signaling exchange process to close the data transmission on the interfered subcarriers. Therefore, according to the embodiments of the present application, the reliability of data transmission can be improved.
