Uncertainty-Aware Radio Map Reconstruction Using Diffusion Models With Sparse Noisy Samples

In large-scale wireless systems, reconstructing radio environment maps (REMs) from sparse measurements is critical for resource management and spectrum allocation. However, practical deployments are often confronted with the challenges of coarse environmental information and noise-contaminated sparse measurements. To a...

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...
