Fast Computation of the DFT In this chapter, fast algorithms for the computation of the DFT, a set of practically efficient DFT algorithms, are presented, both for computing the DFT/IDFT of real- and complex-valued data. The DFT is the workhorse in signal and syste... D Sundararajan 被引...
Ways of efficiently computing the discrete Fourier transform (DFT) when the number of input and output data points differ are discussed. The two problems of determining whether the length of the input sequence or the length of the output sequence is reduced can be found to be duals of each ...
Then, the 2D DFT of the sequence x is given by a 1D DFT of the sequence G along index k for each value of l,X[k,l]=∑m=0M−1G[m,l]WMmk,k=0toM−1andl=0toN−1. This Computation of the 2D FFT on the MAP We implemented the 2D FFT on a recently-introduced commercial...
We propose an improvement of the known DFT-based indexing technique for fast retrieval of similar time sequences. We use the last few Fourier coefficients in the distance computation without storing them in the index since every coefficient at the end is the complex conjugate of a coefficient at...
While the computation efficiency of this new approach is similar to the Hartree-Fock method, the calculation results are much more accurate. The benchmark results presented in the current paper for the bonding and dissociation behaviors of the hydrogen and nitrogen Scientific Reports | 5:13478 | ...

The computation of DFT is transformed to the computation of the first-order moments by the simple mathematical deductions. It is well known that the first-order moments can be computed efficiently using only additions. An efficient systolic array is designed to implement DFT. The comparison with ...
