Demodulation for phase-noise mitigation in 5G and 6G

Non-transitory computer-readable media in a wireless receiver, the media containing instructions that when implemented in a computing environment cause a method to be performed, the method comprising:

• a) receiving a first message comprising message elements, wherein each message element is amplitude modulated and phase modulated according to a first modulation scheme;
• b) determining, according to an error-detection code associated with the first message, that the first message is corrupted;
• c) receiving a second message, and determining, according to a second error-detection code associated with the second message, that the second message is not corrupted;
• d) determining, for each message element of the first and second messages, a raw-signal amplitude and a raw-signal phase;
• e) for each message element, comparing the raw-signal amplitude of the first message to the raw-signal amplitude of the second message, and comparing the raw-signal phase of the first message to the raw-signal phase of the second message;
• and
• f) determining, according to the comparing steps, which message elements of the first message are faulted.

A receiver in a wireless network, the receiver configured to:

• a) receive a particular message element of a wireless message, the particular message element comprising a raw signal, the raw signal modulated according to a modulation scheme, the modulation scheme comprising amplitude modulation multiplexed with phase modulation;
• b) separate the raw signal into an I-branch signal and an orthogonal Q-branch signal;
• c) measure an I-branch amplitude of the I-branch signal and a Q-branch amplitude of the Q-branch signal;
• d) calculate, according to the I-branch amplitude and the Q-branch amplitude, a received sum-signal amplitude and a received sum-signal phase;
• and
• e) demodulate the particular message element according to the received sum-signal amplitude and the received sum-signal phase.
