Modulation schemes for 5G and 6G are disclosed that can be demodulated accurately even when two transmissions collide. The modulation states are configured to reveal the interference and, in most cases, provide an unambiguous determination of the original content. In other cases, when inevitable ambiguities remain, the number of possible states is greatly reduced, enabling rapid selection of the correct state using error-detection codes. The states of the modulation scheme may include phase modulation or amplitude modulation or both, and may be based on classical amplitude-phase modulation or pulse-amplitude modulation. Each state is structured so that any collision, between any two of the states, produces a readily identified amplitude-phase combination, from which the original message and the intruding message can be deduced. Enhanced network throughput and reliability, with fewer retransmission and dropped messages, may result. Many other aspects are disclosed.
