Abstract:
A multichannel time shared demodulator comprising:a grouper for selecting from a first plurality of input channels a second plurality of input channels smaller than said first plurality of input channels, said grouper coupled to a plurality of sources of said first plurality of input channels;a delay filter for providing a peak value sample for each input channel of said second plurality of input channels, said delay filter coupled to said grouper;a demodulator for providing said peak value sample for each input channel of said second plurality of input channels in digital form without Doppler effects, said demodulator coupled to said delay filter and to said grouper;a differential decoder for decoding each peak value sample in digital form to binary information corresponding to information of said second plurality of input channels, said differential decoder coupled to said demodulator; anda unique word correlator for providing a timing signals for indicating said information is to be demodulated and for controlling said differential decoder, said unique word correlator coupled to said demodulator and to said differential decoder.
