Real‐time, fast radio transient searches with GPU de‐dispersion

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 WebThe dedispersion step is typically compiled as part of a larger pipeline, but this repo contains two example programs in the bin/ directory to test and autotune a dedispersion kernel. … poundland acrylic paint https://gironde4x4.com
