Phase-Modulated Carrier Systems TRIZ Cases
- Concurrent Multiband Transceiver RF Front-End Design
RF front-end eliminates tunable components by using phase shifters and matching circuits to enable concurrent multiband operation.
- RF Receiver Spur Suppression via Chirped LO Signals
Chirped local oscillator signals spread spurious energy across frequency bins to mitigate unwanted images without degrading signal-to-noise ratio.
- OTFS Modulation for High-Speed Mobility and Interference Mitigation
Orthogonal Time Frequency Space modulation maps symbols onto two-dimensional basis functions to transform time-varying channels into stable delay-Doppler domains.
