Affine Frequency Division Multiplexing (AFDM) for 6G: Properties, Features, and Challenges
Hyeon Seok Rou, Kuranage Roche Rayan Ranasinghe, Vincent Savaux +3
Affine frequency division multiplexing (AFDM) is an emerging waveform candidate for future sixth generation (6G) systems offering a range of promising features, such as enhanced ro…
6D Rigid Body Localization and Velocity Estimation via Gaussian Belief Propagation
Niclas Führling, Volodymyr Vizitiv, Kuranage Roche Rayan Ranasinghe +4
We propose a novel message-passing solution to the sixth-dimensional (6D) moving rigid body localization (RBL) problem, in which the three-dimensional (3D) translation vector and r…
Joint Channel, Data, and Radar Parameter Estimation for AFDM Systems in Doubly-Dispersive Channels
Kuranage Roche Rayan Ranasinghe, Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu +2
We propose new schemes for joint channel and data estimation (JCDE) and radar parameter estimation (RPE) in doubly-dispersive channels, such that integrated sensing and communicati…
Fast and Efficient Sequential Radar Parameter Estimation in MIMO-OTFS Systems
Kuranage Roche Rayan Ranasinghe, Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu
We consider the estimation of three-dimensional (3D) radar parameters, namely, bearing or angle-of-arrival (AoA), delay or range, and Doppler shift velocity, under a mono-static mu…
From OTFS to AFDM: A Comparative Study of Next-Generation Waveforms for ISAC in Doubly-Dispersive Channels
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, Junil Choi +4
Next-generation wireless systems will offer integrated sensing and communications (ISAC) functionalities not only in order to enable new applications, but also as a means to mitiga…
A New Noncoherent Gaussian Signaling Scheme for Low Probability of Detection Communications
Yuma Katsuki, Giuseppe Thadeu Freitas de Abreu, Koji Ishibashi +1
We propose a novel, Gaussian signaling mechanism for low probability of detection (LPD) communication systems with either single or multiple antennas. The new scheme is designed to…
