PAPR Reduction for AFDM by Affine-Domain Circular Shift without Side Information
The Khai Nguyen, Ebrahim Bedeer
This paper proposes a novel method to reduce the peak-to-average-power-ratio (PAPR) of affine frequency division multiplexing (AFDM) signals without side information (SI). The meth…

Noncoherent Maximum Likelihood Detection for LoRa Signals in Multipath Fading
The Khai Nguyen, Ebrahim Bedeer, Robert Barton
This letter derives the noncoherent (NC) maximum likelihood (ML) detection rule for LoRa signals under Rician multipath fading channels. The proposed NC-ML detection only requires…
