Constellation-Independent Range Estimation in Payload-Based OFDM-ISAC

Christos Masouros, Dongil Yang, Kaitao Meng, Kawon Han

A region-specific mismatched filter lets OFDM-ISAC systems estimate range accurately no matter which data constellation is used for payload.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Simulations across various constellations show that the proposed sensing receiver achieves a ranging MSE approaching the Cramér-Rao bound (CRB), which notably confirms that our design preserves the target ranging performance even under the non-constant-modulus constellation.

C2weakest assumption

The delay region of interest can be accurately prescribed in advance so that sidelobe suppression is applied only within that region without distorting the mainlobe response for targets inside it.

C3one line summary

The ROI-MMF enables constellation-independent range estimation in OFDM-ISAC by suppressing sidelobes in a prescribed delay region, achieving near-CRB MSE performance with an efficient Woodbury-based implementation.
