PAPR Reduction for OFDM-ISAC Signals via Frequency-Domain Multiple Degree-of-Freedom Waveform Enhancement
This paper studies peak-to-average power ratio (PAPR) reduction for orthogonal frequency division multiplexing (OFDM) integrated sensing and communication (ISAC) signals. We propose active constellation extension with constant-modulus tone reservation (ACE-CMTR), which constrains the reserved tones to have constant mod...
