How does overlap-add work?
The overlap-add method breaks a long sequence, x(n) , into signals of shorter length and calculates the convolution of each block independently. To arrive at the final result, we need to apply an appropriate time shift to the convolution of the blocks and add them together.
What is overlap-add method in DSP?
What is the the overlap-add method? The overlap-add method is based on the fundamental technique in DSP: (1) decompose the signal into simple components, (2) process each of the components in some useful way, and (3) recombine the processed components into the final signal.
