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 and overlap-add introduce a processing latency of N-M+1 samples. You can reduce this latency by partitioning the numerator into shorter segments, applying overlap-add or overlap-save over the partitions, and then combining the results to obtain the filtered output[3]. The latency ...

When two signals or images to be correlated or convolved are of different sizes, overlap-add (OLA) and overlap-save (OLS) algorithms are often employed to reduce computational complexity. In this paper, we investigate the use of these algorithms for multidimensional correlations required in many ...

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...

Modified overlap-save and overlap-add algorithms for filtering a real signal by an N-tap finite impulse response filter are delineated. These algorithms compute two N-sample output blocks simultaneously at every processing step using 2N-point transforms, while the traditional methods compute only one...
