Abstract

Systems and methods for operating a multi-channel intercom system for audio communications between users, with reduced crosstalk, are disclosed. Exemplary implementations may: receive, by a first user station, a modulation carrier signal; capture a first audio signal from a first user, wherein the first audio signal has a first phase; at a rate based on the modulation carrier signal, invert the first phase of the first audio signal to generate a phase-flipped audio signal; transfer the phase-flipped audio signal to a second user station; at a second rate based on the modulation carrier signal, invert a phase of the phase-flipped audio signal to generate an intermediate audio signal; and present a second audio signal based on the intermediate audio signal to the second user.
