Example B1 Prompt Excerpt¶
You are implementing a soft-input decoder for a binary polar code over a
BPSK-AWGN channel. The reference decoder is Tal & Vardy's SC-List (SCL)
algorithm with CRC-aided final selection; the obvious single-path SC
decoder is 1-2 dB worse and will lose significant credit.
## Inputs (read-only)
- `./data/received_llr.npy` — channel log-likelihood ratios per codeword,
shape `(num_cases, n_codewords_per_case, N)`, dtype `float32`.
Convention: `LLR = log P(y|bit=0) - log P(y|bit=1)`, so **positive LLR
