Digital circuit arrangement for the vicinity of the bearings, have realization of a gmsk modulation (gaussian minimum shift keying) - modulation

摘要

the invention relates to a digital schaltungsanordnung for implementation of a gmsk (gaussian minimium zones shift keying) modulation, in a sequence of binary eingangswerten with a linear filter arrangement (2) a series of imaginary and a series of real baseline is generated.a phasengenerator (1) in dependence on the second consecutive binary input values to the real numbers 1 or - 1, or the imaginary numbers j or j as a binary encoded phasengeneratorwerte.in the phasengenerator in equality of two consecutive eingangswerten figures in positive sequence from 1 to j or j to - 1 or - 1 to - 3 or - j to 1 and inequality of two consecutive eingangswerten in reverse negative sequence. changes. the linear filter arrangement receives the phasengeneratorwerte.
