US 2024/0421847 A1 · SYNTHESIZING COMPOSITE SIGNALS

Abstract

A technique for generating electronic signals includes processing a respective first-level input signal by each of a plurality of first-level channels, including up-sampling the respective first-level input signal and single-sideband (SSB) modulating the up-sampled first-level input signal to produce a respective first-level output signal. The technique further includes processing a respective second-level input signal by each of a plurality of second-level channels, including up-sampling the respective second-level input signal and SSB-modulating the up-sampled second-level input signal to produce a respective second-level output signal. The plurality of second-level channels is arranged in multiple groups assigned to respective first-level channels, and the technique further includes (i) summing together the second-level output signals of the second-level channels in each group, (ii) providing a group sum as the first-level input signal to the first-level channel to which the group is assigned, and summing together the first-level output signals to provide a composite signal.
