The International Nuclear Information System is operated by the IAEA in collaboration with over 150 members. 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. This subtle difference is important—incoherent dedispersion is only an approximation that is valid under
