In this paper, we address the design of distributed coding schemes for the 3-node relay
channel with half-duplex constraint. We first discuss the general problem of optimally re …

This correspondence studies coding strategies for a three-node relay channel. We start with
the basic coding strategies of Cover and El Gamal: the relay decodes the source message …

The multiuser communication channel, in which multiple users exchange information with
the help of a relay terminal, termed the multiway relay channel (mRC), is introduced. In this …

We propose Low Density Parity Check (LDPC) code designs for the half-duplex relay
channel. Our designs are based on the information theoretic random coding scheme for …

We introduce an extension of the relay channel that we call two-way relay channel. The two-
way relay channel consists of two users which want to communicate to each other with the …

This paper describes techniques to decompose LT codes (a class of rateless erasure-
correcting codes) into distributed LT (DLT) codes. DLT codes can be used to independently …

We propose a new signal-processing scheme, referred to as Decode-Compress-and-
Forward with Selective-Cooperation (DCF-SC). In DCF-SC, the relay dedicates a certain …

Upper and lower bounds on the capacity and minimum energy-per-bit for general additive
white Gaussian noise (AWGN) and frequency-division AWGN (FD-AWGN) relay channel …

The goal of this article is to discuss the implementation of two cooperative protocols-decode-
and-forward (DF) and estimate-and-forward (EF). In each case, the starting point is an …

We introduce a new two-step relaying scheme based on superposition coding, SC-relaying.
In Step 1, the source AS broadcasts a message, created by superposition coding, to the …
