Abstract:
1. A process for receiving a broadband electromagnetic signal, comprising: dividing the receiving spectrum into n partial spectrums, with n>1; parallel further processing of thus obtained n partial signals in n channels; demodulating the n partial signals into the base band; n equal-type analog-to-digital converters performing an analog-to-digital conversion of the n partial signals; amplitude and phase correcting the n partial signals for compensating interfering edge effects at the transition to the respectively adjacent channel; spectral transformation of the n partial signals in the n parallel channels using n Fast Fourier Transforms FFT; integration of the partial spectrums of the n partial signals to form a total spectrum in the frequency domain; and extraction of individual frequency bands from the total spectrum which, while a multiplexer is used, are in each case fed to one of several parallel further processing channels.
