Pragmatic distributed algorithm for spectral access in cooperative cognitive radio networks [PDF]
, 2014 A pragmatic distributed algorithm (PDA) is proposed for supporting the efficient spectral access of multiple Primary Users (PUs) and Cognitive Users (CUs) in cooperative Cognitive Radio (CR) networks. The novelty of our PDA is that the PUs negotiate with

Reed-Solomon Coded Cooperative Spatial Modulation Based on Nested Construction for Wireless Communication [PDF]
Radioengineering, 2021 This paper proposes the Reed-Solomon coded cooperative spatial modulation (RSCC-SM) scheme based on nested construction of two Reed-Solomon (RS) codes over quasi-static Rayleigh fading channel.

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

Opportunistic Cooperative Multicast Based on Coded Cooperation
IEICE Transactions on Communications, 2011 In this letter, we study cooperative transmission in wireless multicast networks. An opportunistic cooperative multicast scheme based on coded cooperation (OCM-CC) is proposed and its closed-form expression of outage performance is obtained. Through numeric evaluation, we analyze its outage probability with different numbers of relays and different ...

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 ...

Near-Capacity Irregular Bit-Interleaved Coded Modulation [PDF]
, 2008 An Irregular Bit-Interleaved Coded Modulation based Iterative Decoding (Ir-BICM-ID) aided scheme is proposed. The irregularity of the scheme pervades the three basic components of BICM-ID, namely the encoder, the unity-rate precoder and the bit-to-symbol

Improved coded cooperation schemes for wireless communications [PDF]
, 2008 Cooperative communications can exploit distributed spatial diversity gain to improve link performance. When the message is coded at a low rate, source and relay can send different parts of a codeword to destination.
