Overlap-add & Overlap-save method Bear-boy stay hungry, stay foolish46 人赞同了该文章 OLA & OLS 利用圆周卷积与线性卷积的关系,在频域通过FFT是快速计算卷积的方法之一。但当参与卷积的序列长度相差较多,如常见的音频系统,输入序列通常是麦克风拾取到的数据,输入序列长度会很长,此时需要对另外一个序列补较多的...
overlap-save methodSampling rate conversionThe overlap-add (OLA) and overlap-save (OLS) methods are well known as efficient schemes for higher-order filtering. In those methods, the linear convolution for the infinite-duration data is reduced to the circular convolution for the finite blocks, and...

It can speed up the computation of 2D discrete wavelet transform. (2) In two-dimensional overlap-save method directly calculating the FNTT to the whole input sequence may meet two difficulties; namely, a big modulo obstructs the effective implementation of the FNTT and a long input sequence ...
save methodIn this paper, we propose two parallel processing methods for multidimensional (MD) sampling lattice alteration. The use of our proposed methods enables us to alter the sampling lattice of a given MD signal sequence in parallel without any redundancy caused by up- and down-sampling, ...
Overlap Save Method In this method, the size of the input data blocks is N=L+M-1 and the DFTs and the IDFTs are of length L. Each Data Block consists of the last M-1 data points of the previous block followed by L new data points to form a data sequence of length N=L+M-1...

( n 1=0,1,…,l 1,n 2=0,1,…,m 1-1) are the input and output of the filter,respectively.In many DSP applications the lengths l 1 and m 1 are very long but lengths l 2 and m 2 are short.So, if using overlap save method to calculate y n 1,n 2 which is the convolution...
