The computation of NNFFT is mainly based on the nonuniform fast Fourier transform with nonequispaced spatial nodes and equispaced frequencies (NFFT). The NNFFT employs two compactly supported, continuous window functions. For fixed nonharmonic bandwidth, we show that the error of the NNFFT with two sinh -type window functions has an exponential decay with respect to the truncation parameters of the used window functions. As an important application of the NNFFT, we present the fast sinc transform. 2023-03-31T01:53:42Z 2023-03-31T01:53:42Z 2023 Book https://link.springer.com/article/10.1007/s11075-022-01389-6 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7361 en application/pdf Springer |
