Data Provenance

Release identity

• Dataset: Scene2Wave
• Dataset version: 1.0.1
• Rightsholder: Pengcheng Laboratory
• Authors: Mengfan Zheng; Liwen Jing; Tingting Yang; Li Sun; Yuxuan Shi; Ping Zhang; Leiyang Xu; Jianjun Chen
• Formal samples: 100
• Source experiment: 2026-08-01_rf_main_training_full_v2
• Source generator revision: 995f6fd60a65c69e844c994ab572dac83850b95e
• Packaging/viewer checkpoint: new-rf-compiler-v1.8 (57c7fb0)

The source generator revision records the code used for the data itself. The later v1.8 checkpoint adds release packaging, validation, and the static demo; it does not claim that the 100 samples were regenerated with v1.8.

Generation stack

• CARLA 0.9.16
• Sionna 0.19.2
• Four Towns: Town01, Town02, Town03, Town15
• Carrier: 3.7 GHz
• Bandwidth: 15.36 MHz
• 512 subcarriers at 30 kHz spacing
• CSI/CIR geometry rate: 2 kHz

The complete generation policy is preserved in metadata/generation_config.yaml. Dataset distributions and source manifest identity are recorded in dataset_info.json.

Qualification and export

CARLA candidate geometry was closed and qualified before Sionna processing. The public export contains only the 100 formal samples and removes visual QA, worker logs, cache keys, candidate data, and intermediate artifacts. The Hub package wraps each complete sample in a deterministic tar without altering its internal sensor or wireless files.
