Abstract

A method and a device for joint suppression of narrowband and multiple access interference are provided. The method includes: performing time domain windowing processing on a received signal, and performing frequency domain interference processing on a signal after windowing processing to obtain a matched filter and a time domain signal; obtaining reconstructed baseband received data for a signal of each channel; obtaining reconstructed signals after matched filtering; accumulating the reconstructed signals of multiple channels to obtain a reconstructed accumulated value, obtaining a compensation value according to a difference between the time domain signal and the reconstructed accumulated value, and compensating the reconstructed signals with the compensation value to obtain an actual received signal of the each channel; and outputting a joint suppression result.
