Support Quality … WebJan 1, 2024 · Coherent dedispersion is a convolution of the raw signal voltages (Nyquist sampled time-series) with the inverse of the transfer function of the interstellar medium (ISM). The convolution is most efficiently performed as a multiplication in the frequency domain through the discrete convolution theorem (see Press et al., 1992 Chapter 13.1).

WebThe term incoherent dedispersion refers to applying frequency-dependent time delays to the I()tf, matrix, while coherent dedispersion involves applying a frequency-dependent phase shift to the Fourier transform of the raw voltage signal.
