Patent ID: 11777547

Abstract:
To provide improved phase noise tolerance and improved identification of certain fault types, a modulation/demodulation procedure is disclosed for 5G and 6G. The transmitter can modulate a message according to the amplitude and phase of the overall waveform to be emitted, modulated according to predetermined amplitude and phase levels of the modulation scheme. The receiver can then separate the received waveform into orthogonal I and Q branches and measure their branch amplitudes, as usual. The receiver can then convert the branch amplitude measurements back into the original amplitude-phase modulation parameters using formulas provided. The receiver can then demodulate the message by comparing the overall amplitude and phase of each message element to the predetermined amplitude and phase levels of the modulation scheme, which thereby provides substantially increased phase noise tolerance at high frequencies. The procedure can also diagnose fault types and identify faulted message elements specifically, among other benefits.
