Code designs for cooperative communication
IEEE Signal Processing Magazine, 2007 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 information theoretic random coding scheme, which motivates a practical code construction.

Position estimation of mobile robots based on coded infrared signal transmission [PDF]
, 1997 A system based on coded infrared signal transmission for the estimation of position of mobile robots in a structured environment is reported. Particular emphasis is placed on the polar coordinate arrangement in which signals are sent from the ...

On coding for cooperative data exchange [PDF]
IEEE Information Theory Workshop 2010 (ITW 2010), 2010 We consider the problem of data exchange by a group of closely-located wireless nodes. In this problem each node holds a set of packets and needs to obtain all the packets held by other nodes. Each of the nodes can broadcast the packets in its possession (or a combination thereof) via a noiseless broadcast channel of capacity one packet per channel use.

Split-extended LDPC codes for coded cooperation [PDF]
2010 International Symposium On Information Theory & Its Applications, 2010 We propose a new code design that aims to distribute an LDPC code over a relay channel. It is based on a split-and-extend approach, which allows the relay to split the set of bits connected to some parity-check of the LDPC code into two or several subsets. Subsequently, the sums of bits within each subset are used in a repeat-accumulate manner in order

Generalized Network-Coded Cooperation in OFDMA Communications
IEEE Access, 2018 Cooperative communication is a well-established technique to obtain diversity and consequently combat the fading inherent to the wireless channel. In a recent work, network-coded cooperation (NCC) along with graph theory-aided subcarrier allocation was ...

Energy-Aware Cross-Layer Offloading in Fog-RANs Using Network Coded Device Cooperation
IEEE Access, 2020 This paper studies a Fog Radio Access Network (F-RAN) architecture that utilises the increasing storage and device-to-device communication capacities of users' smart devices (referred to as F-UEs) in order to reduce the time that the central processing ...

Centralized Coded Caching with User Cooperation
, 2019 In this paper, we consider the coded-caching broadcast network with user cooperation, where a server connects with multiple users and the users can cooperate with each other through a cooperation network.
