| Abstract: | To improve convergence speed and accuracy of LMS algorithm, the paper proposes fast adaptive filter algo- rithm based on overlapping storage. Use a fast convolution technique of the overlapping storage method to achieve fast Fourier transform. The theoretical analysis and computer simulation show that the improved algorithm has faster conver- gence and better steady state performance and accurate estimation is superior other algorithm. |
| Keywords: | overlapping storage least-mean-squares adaptive filter Fourier transform |
