Methods for demodulating wireless messages in 5G and 6G include comparing signal parameters of the message to a demodulation reference that is placed in close proximity to the message. The demodulation reference and the message may be transmitted in a concatenated fashion on a series of subcarriers at a single symbol-time, or on a series of symbol-times at a single subcarrier. The receiver may measure and record waveform parameters of the message signal as it is received, for subsequent separation and demodulation of the various message elements. The message may be modulated using classical amplitude-phase modulation, or pulse-amplitude modulation, or other modulation scheme. In each version, the receiver can measure the wave properties (amplitude and phase, branch amplitudes, etc.) of the demodulation reference, and then compare the same parameters of the message elements, thereby demodulating the message regardless of the modulation scheme.
