Abstract

The present application discloses a narrowband signal processing method, device and storage medium, the method relates to the technical field of interference signal processing, and solves the problem of excessive resource consumption in the prior art; the method includes: receiving a signal to be processed, processing Perform serial / parallel signal transformation on the processed signal, and perform window processing on the transformed signal to determine the continuous signal to be processed; perform FFT transformation on the continuous signal to be processed to determine the FFT transformed signal; divide the FFT transformed signal into two channels, one channel The FFT transformed signal generates a frequency domain weighted vector, and the frequency domain weighted vector is subjected to frequency domain weighting processing with another FFT transformed signal to determine the frequency domain weighted signal; the frequency domain weighted signal is subjected to IFFT transformation to determine the IFFT transformed signal; the IFFT transform The signal undergoes serial / parallel conversion to determine the processing completed signal; it realizes the processing of the interference signal in the narrowband signal, improves the signal-to-interference ratio of the received signal, reduces the use of hardware, and consumes less corresponding resources.

Description

technical field [0001] The present application relates to the technical field of interference signal processing, and in particular, to a method, an apparatus, and a storage medium for processing a narrowband interference signal. Background technique [0002] Spread spectrum technology has been widely used in information transmission, and its characteristic is that the bandwidth used to transmit information is much larger than the bandwidth of the information itself. The expansion of the frequency band is completed by an independent code sequence, which is realized by the method of coding and modulation. It has nothing to do with the transmitted data information. The same code is used at the receiving end to receive, despread and restore the transmitted information data. [0003] At present, the spread spectrum technology is susceptible to the interference of various electromagnetic waves, and how to remove the interference has become a key issue. Now, the processing of the i...
