Movable Antenna-Enhanced MIMO-OFDM ISAC: Ambiguity Function Analysis, Waveform Design and Antenna Position Optimization

Multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) provides abundant spatial and time-frequency degrees of freedom for integrated sensing and communication (ISAC), while movable antennas (MAs) further introduce reconfigurable spatial freedom through array geometry adjustment. However,...

Index Modulation Aided Phase-Rotated AFDM for Efficient Integrated Sensing and Communication: Framework, Optimization and Performance Analysis

Affine frequency division multiplexing (AFDM) has emerged as a competitive waveform for integrated sensing and communication (ISAC) in high-mobility scenarios, but its data-dependent high peak-to-average power ratio (PAPR) and ambiguity function (AF) sidelobes may degrade the power-amplifier efficiency as well as the s...

Learning-Based Symbol-Level Precoding for Flexible Tradeoffs in MIMO-ISAC Systems

Integrated sensing and communication (ISAC) has emerged as one promising candidate for 6 G wireless networks, yet it encounters difficulties in alleviating mutual interference in complex multi-user and multi-target scenarios. To address this issue, one feasible methodology is symbol-level precoding (SLP) that exploits...
