Channel switch operating in the frequency domain, particularly suitable for satellite applications

摘要

Channel switch, operating in the frequency domain, particularly suitable for satellite applications, essentially consisting (Fig. 3) of calculation processors (7) (DFT), a switching matrix (10), other calculation processors (IDFT). This switch is particularly suited for the switching of transmission channels, through the application of specific algorithms used in digital signal processing. The invention can be applied all sectors envisaging a transmission channel switching unit, some sets of input channels and some sets of output channels. In each set, the channels are distinguished by the frequency band they occupy. The invention is particularly useful for communications satellites, since it allows significant reductions in weight and in power consumption with respect to previous solutions.
