Data transmission process of the QTT ultrawideband low-frequency digital backend system. Signals from the ultrawideband receiver are sampled and channelized by FPGA boards, then transmitted over a 100 GbE switch to a GPU cluster for parallel processing (fast Fourier transform (FFT), channelization, dedispersion, inverse FFT (IFFT), integration and storage.
