Statistical Ambiguity-Function-Aware Joint Beamforming and Subcarrier Allocation for MIMO-OFDM ISAC under Random Symbols
Wonill Kim, Yumin Kim, Hyeonsu Lyu +1
Ambiguity function (AF) characterizes the delay--Doppler sidelobe structure that governs target resolution and masking in radar sensing. In ISAC, however, random communication symb…

End-to-End Secure Connection Probability in MultiLayer Networks with Heterogeneous Rician Fading
Hyeonsu Lyu, Yumin Kim, Hyun Jong Yang
Ensuring physical-layer security in non-terrestrial networks (NTNs) is challenging due to their global coverage and multi-hop relaying across heterogeneous network layers, where th…
