Numerical Stability of DFT Computation for Signals with Structured Support
Charantej Reddy Pochimireddy, Aditya Siripuram, Brad Osgood
We consider the problem of building numerically stable algorithms for computing Discrete Fourier Transform (DFT) of - length signals with known frequency support of size . A…
Fast DFT Computation for Signals with Structured Support
Charantej Reddy P, Aditya Siripuram, Brad Osgood
Suppose an length signal has known frequency support of size . Given sample access to this signal, how fast can we compute the DFT? The answer to this question depends on th…
Computing the Discrete Fourier Transform of signals with spectral frequency support
P Charantej Reddy, V S S Prabhu Tej, Aditya Siripuram +1
We consider the problem of finding the Discrete Fourier Transform (DFT) of length signals with known frequency support of size . When is a power of 2 and the frequency…
