Abstract.
The causes of frequency determination ambiguity in matrix receiver are
considered: a presence of channel filter parasitic pass bands, a small slope of
amplitude-frequency characteristic of channel filters, a receiving of time
matched signals with different frequencies. The analysis of efficiency of
possible frequency ambiguity reduction ways is performed. The way of frequency
ambiguity reduction in receiving of time matched signals with different
frequencies is proposed.
Key words:
ambiguity, matrix receiver, parasitic pass band, channels joint,
amplitude-frequency characteristic slope, binary detector, selectivity, rough
frequency determination, frequency determination ambiguity, even channels.
