Directional noise suppression method based on assigned bandwidth

The invention discloses a directional noise suppression method based on an assigned bandwidth. The directional noise suppression method is characterized in that step 1, a target voice channel transmission function can be estimated according to an expected evaluation value of a power spectrum of a transmission channel; step 2, a smooth noise component can be estimated and suppressed, and a voice blocking filter can be defined, and a target voice can be blocked, and the smooth noise component can be acquired, and then a target voice spectrum after the suppression of the smooth noise can be calculated; step 3, the directional noise can be suppressed, and the phase difference between the target voice and the observed voice can be determined, and when the observed voice of the current time frequency unit is the dominant directional noise, which can be filtered by using a band-pass filter; and finally, the target voice signal used for suppressing the smooth noise and the directional noise can be acquired; The directional noise suppression method based on the assigned bandwidth is advantageous in that the system is simple, and the difference between the directional noise and the smooth noise component can be effectively distinguished during the noise suppression process, and then based on the different natures, the suppression can be carried out by adopting different methods, and therefore the noise suppression effect is better, and the high applicability can be provided.
