We consider transmission over a wiretap channel where both the main channel and the wiretapper’s channel are Binary Erasure Channels (BEC).
Secret Sharing LDPC Codes for the Constrained Gaussian Wiretap Channel
Secret Sharing LDPC Codes Constrained Gaussian Wiretap Channel
font style='font-size:12px;'>
2010/12/7
The problem of secret sharing over the Gaussian wiretap channel is considered. A source and a
destination intend to share secret information over a Gaussian channel in the presence of a wiretapper wh...

2010/12/6
We study incremental redundancy hybrid ARQ (IR-HARQ) schemes based on punctured, finite-length, LDPC codes. The transmission is assumed to take place over time varying binary erasure channels, such as...

2010/12/10
In this paper, we introduce an efficient method for the joint linear-programming (LP) decoding of low-density parity-check (LDPC) codes and finite-state channels (FSCs). In particular, we extend the a...
