Wideband Index Modulation with Circularly-Shifted Chirps
Safi Shams Muhtasimul Hoque, Chao-Yu Chen, Alphan Sahin
In this study, we propose a wideband index modulation (IM) based on circularly-shifted chirps. To derive the proposed method, we first prove that a Golay complementary pair (GCP) c…
Index-Modulated Circularly-Shifted Chirps for Dual-Function Radar & Communication Systems
Safi Shams Muhtasimul Hoque, Alphan Sahin
In this study, we analyze index modulation (IM) based on circularly-shifted chirps (CSCs) for dual-function radar & communication (DFRC) systems. We develop a maximum likelihood (M…
DFT-spread-OFDM Based Chirp Transmission
Alphan Sahin, Nozhan Hosseini, Hosseinali Jamal +2
In this study, we propose a framework for chirp-based communications by exploiting discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-s-OFDM). We sho…
RL-Based Interference Mitigation in Uncoordinated Networks with Partially Overlapping Tones
Mrugen Deshmukh, Md Moin Uddin Chowdhury, Sung Joon Maeng +2
Partially-overlapping tones (POT) are known to help mitigate co-channel interference in uncoordinated multi-carrier networks by introducing intentional frequency offsets (FOs) to t…
Golay Layer: Limiting Peak-to-Average Power Ratio for OFDM-based Autoencoders
Alphan Sahin, David W. Matolak
In this study, we propose a differentiable layer for OFDM-based autoencoders (OFDM-AEs) to avoid high instantaneous power without regularizing the cost function used during the tra…
