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…
ELF Codes: Concatenated Codes with an Expurgating Linear Function as the Outer Code
Richard Wesel, Amaael Antonini, Linfang Wang +3
An expurgating linear function (ELF) is a linear outer code that disallows the low-weight codewords of the inner code. ELFs can be designed either to maximize the minimum distance…
Achievable Rates and Low-Complexity Encoding of Posterior Matching for the BSC
Amaael Antonini, Rita Gimelshein, Richard Wesel
Horstein, Burnashev, Shayevitz and Feder, Naghshvar et al. and others have studied sequential transmission of a K-bit message over the binary symmetric channel (BSC) with full, noi…
Sequential Transmission Over Binary Asymmetric Channels With Feedback
Hengjie Yang, Minghao Pan, Amaael Antonini +1
In this paper, we consider the problem of variable-length coding over the class of memoryless binary asymmetric channels (BACs) with noiseless feedback, including the binary symmet…
Neural Normalized Min-Sum Message-Passing vs. Viterbi Decoding for the CCSDS Line Product Code
Jonathan Nguyen, Linfang Wang, Chester Hulse +5
The Consultative Committee for Space Data Systems (CCSDS) 141.11-O-1 Line Product Code (LPC) provides a rare opportunity to compare maximum-likelihood decoding and message passing.…
Causal (Progressive) Encoding over BinarySymmetric Channels with Noiseless Feedback
Amaael Antonini, Rita Gimeshein, Richard D. Wesel
Traditional channel coding with feedback constructs and transmits a codeword only after all message bits are available at the transmitter. This paper joins Guo & Kostina and Lalith…
