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).
