OLA(Overlap-add method)重叠相加法,其基本思路是将输入序列x(n)按照时间顺序分割为多段长度为L的子序列xk(n),通过计算每个子序列xk(n)与h(n)的卷积结果yk(n)=xk(n)∗h(n),最终将每个yk(n)按照一定的规律重叠累加(这也是OLA中Overlap add的含义),即可得到x(n)与h(n)的卷积结果。 1.1 OLA原理 设...

重叠-相加之卷积法 ( Overlap-add method ) 是一种区块卷积 ( block convolution, sectioned convolution )，可以有效的计算一个很长的信号 x[n] 和一个 FIR 滤波器 h[n] 的离散卷积。形式 其中h[m] 在 [1,M] 之外为零。重叠-相加之卷积法算出重叠的输出区块；另一种区块卷积的作法，重叠-存储之卷积...
