English Description：
Application background in & nbsp; signal processing, & nbsp; overlap add method (OA, OLA) & nbsp; is an effective way to evaluate discrete & nbsp; convolution & nbsp; a very long signal & nbsp; & nbsp; a & nbsp; finite impulse response & nbsp; & nbsp; (FIR) filter;: where and where, [M] = 0, in contrast, outside the region [1, M]. The key technology of signal & nbsp; & nbsp; is the first segmentation into non overlapping sequences, and then & nbsp; discrete Fourier transform & nbsp; Sequence & nbsp; & nbsp; is the evaluation multiplied by FFT & nbsp; & nbsp
