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…
Low Complexity Algorithms for Transmission of Short Blocks over the BSC with Full Feedback
Amaael Antonini, Hengjie Yang, Richard D. Wesel
Building on the work of Horstein, Shayevitz and Feder, and Naghshvar \emph{et al.}, this paper presents algorithms for low-complexity sequential transmission of a -bit message o…
