2
+
3
+ **Description:** OTFS+LDPC OTA, fc=2.45 GHz, tx_gain=-5 dB, 500 caps, after deterministic Pluto gain reset (3x gain rewrite); channel below LDPC cliff so 0/500
4
+
5
+ **Key result:** 0/500 = 0.0% (snr_post median ~-4 dB)
6
+
7
+ **Source:** `/tmp/otfs_ldpc_n5_v2/run_otfs_rx_20260531_161601`
8
+
9
+ **Stats:** 502 files, 82.7 MB
10
+
11
+ **Common columns in each `cap_*.npz`:**
12
+ - `rxw` (complex64) — raw RX samples (one capture window)
13
+ - `meta_json` (str) — per-capture metadata: cfo_hz, pilot_rx, snr_post, etc.
14
+ - (OFDM step10 only) `Yeq_data` (complex64, shape `(num_syms, 48)`) — equalised data subcarrier symbols ready for LDPC post-decode
15
+
16
+ **Filename suffix convention:** `_ok` = packet decoded, `_fail`/`_bg` = decode failed / pure background.
17
+
18
+ **Reproducibility:** see `../README.md` (top-level dataset card) and the paper, [`globecom2026_otfs_doppler.pdf`](https://github.com/lkk688/RF-Stream-PHY/tree/main/OTFS/paper).
