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...

The overlap-add method (OLA) and overlap-save method (OLS) are well known as efficient schemes for high-order FIR filtering. In this paper, new sampling rate conversion methods are proposed by extending the OLA and OLS, and eliminating the redundancy caused by the conversion. First, for ...
processing latency of 213 samples. The fifth plot shows the signal filtered using the overlap-save method. The filtered signal shows a latency of 30 samples since the partition length of the overlap-save method is now 30. This partition value is less than the original partition length of 213...
overlap-addsave 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-...
