Joint iterative decoding of LDPC codes for channels with memory and erasure noise
This paper investigates the joint iterative decoding of low-density parity-check (LDPC) codes and channels with memory. Sequences of irregular LDPC codes are presented that achieve...

Secret Sharing LDPC Codes for the Constrained Gaussian Wiretap Channel
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 presenc...

On the Capacity of One-Sided Two User Gaussian Fading Broadcast Channels
In this paper, we investigate upper and lower bounds on the capacity of two-user fading broadcast channels where one of the users has a constant (non-fading) channel. We use the Co...

Multi-user OFDM Based on Braided Convolutional Codes
Abstract Braided convolutional codes (BCCs) form a class of iteratively decodable convolutional codes that are constructed from component convolutional codes. In braided code divis...
