A 5G mobile communication digital modulation signal generating device and its generating method

Abstract

The invention discloses a 5G mobile communication digital modulating signal generation device and a generation method thereof. The 5G mobile communication digital modulating signal generation device comprises a multigroup data bit flow channel, for processing multigroup data bit flows; a synthesizing unit, for synthesizing multiple signals into an IQ signal in the time domain; an IQ modulation unit, for modulating the IQ signal into radio frequency; a frequency conversion unit, for converting frequencies for generating 5G signals of various frequencies; and a power control unit, for automatically setting power levels of output signals according to user demands. The multigroup data bit flows are synthesized by the synthesizing unit, and then output after being processed by the IQ modulation unit, frequency conversion unit and the power control unit connected in sequence. According to the 5G mobile communication digital modulating signal generation device and the generation method thereof, by using the multi-path baseband signal synthesis technology, complexity of generation of 5G mobile communication digital modulating signals is reduced, shaping filter is combined to eliminate the signal interference problem among multiple paths, and thereby the 5G mobile communication digital modulating signals with controllable signal bandwidth and extent and freely selectable frequency are generated, and technical support is provided for the development of the 5G system.
