Abstract :
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 finite-duration sequences, a rate conversion with the DFT-domain approach is discussed. Next, using the result, the extended OLA and OLS are proposed for infinite-duration sequences. Finally, the computation complexities of our proposed methods are shown
