Abstract

Wireless messages in 5G and 6G are generally transmitted on one polarization orientation, the vertical orientation, while the horizontal polarization is generally unused. Disclosed are modulation schemes and systems for encoding additional information in the horizontal polarization signal as well as the vertical, thereby providing faster and more compact messaging. Also disclosed are short-form polarization-demodulation references that exhibit the maximum and minimum amplitude levels of the modulation scheme, in the vertical and horizontal polarizations separately, while the other polarization is silent. The receiver can thereby measure and correct for crosstalk between the polarization components. The demodulation reference may also include a gap of zero transmission, enabling background evaluation. By comparing the modulation values of message elements to the predetermined levels exhibited in the polarization-demodulation reference, the receiver can demodulate the message while mitigating noise, interference, and crosstalk, according to some embodiments.
