Phase-Modulated Carrier Systems TRIZ Cases
- Differential Modulation With ±π/2 Phase Transitions for Low PAPR
A differential modulation scheme limits phase transitions to ±π/2, reducing PAPR and power amplifier consumption in radio transmission.
- Data Modulation Constellation Scaling for 5G Amplifier Linearity
A modulation parameter scales constellation symbols by mode, limiting amplifier distortion and out-of-band leakage.
- Channel Coding with Non-Uniform Modulation for Nonlinear Channels
Non-uniform constellation probabilities improve 5G spectral efficiency on nonlinear channels.
