Noise mitigation by guard-space reference calibration in 5G and 6G

A method for a wireless receiver, the method comprising:

• a) receiving a message comprising message elements, each message element comprising a single resource element of a resource grid, the resource grid comprising symbol-times in time and subcarriers in frequency, wherein each message element comprises a guard-space reference followed by message data;
• b) for each message element, measuring a reference modulation of the guard-space reference;
• c) for each message element, comparing the reference modulation to a predetermined modulation;
• d) for each message element, determining, according to the comparing, a correction comprising a difference between the reference modulation and the predetermined modulation;
• e) for each message element, measuring a message modulation of the message data;
• and
• f) for each message element, correcting the message modulation according to the correction.

A method for a wireless receiver, the method comprising:

• a) determining a modulation scheme comprising amplitude modulation according to a plurality of predetermined amplitude levels;
• b) receiving a frequency-spanning message comprising message elements, wherein the message elements occupy successive subcarriers of a single symbol-time of a resource grid;
• c) wherein each message element comprises a guard space followed by message data, the guard space comprising a guard-space reference signal;
• d) for each message element, determining a reference amplitude and a reference phase of the guard-space reference signal, and calculating a plurality of modulation levels according to the reference amplitude or the reference phase;
• e) for each message element, determining a message amplitude and a message phase of the message data;
• and
• f) demodulating the message data by comparing the message amplitude or the message phase to the plurality of modulation levels.
