Efficient Probabilistic Parity Shaping for Irregular Repeat-Accumulate LDPC Codes
Diego Lentner, Thomas Wiegart, Richard D. Wesel
Algorithms are presented that efficiently shape the parity bits of systematic irregular repeat-accumulate (IRA) low-density parity-check (LDPC) codes by following the sequential en…

Feedback Communication Over the BSC with Sparse Feedback times and Causal Encoding
Amaael Antonini, Rita Gimelshein, Richard D. Wesel
Posterior matching uses variable-length encoding of the message controlled by noiseless feedback of the received symbols to achieve high rates for short average blocklengths. Tradi…
