AI Technical Summary
In existing technologies for high-frequency radio signal transmission, the peak-to-average power ratio (PAPR) is too high, resulting in low efficiency of the transmitter power amplifier and insufficient robustness to phase changes, especially at frequencies above 6 GHz.
The polarized constellation modulation method is adopted to reduce the peak-to-average power ratio (PAPR) of multi-carrier symbols by phase rotation of the block modulation points of multi-carrier symbols, and to improve the system's robustness to phase changes by constructing a polarized constellation.
It effectively reduces the PAPR of multi-carrier symbols, improves the system's phase change robustness and noise immunity at high frequencies, and is suitable for high-frequency radio signal transmission.
