Novel half-coherent receivers for amplify-and-forward relaying

, 2012
Consider a system in which the signal is transmitted from the source to the destination via an amplify-and-forward relay. For such a system, we derive in this paper, novel receivers that have complete knowledge of either the source-relay link or the ...

EFFECTS OF THE NUMBER OF RELAY ANTENNAS AND RELAY-POWER ON MIMO PRECODED TWO-WAY RELAYING [PDF]

ICTACT Journal on Communication Technology, 2011
In this treatise a two-way Amplify and Forward (AF) relay-aided system is considered, which employs the so-called Arithmetic Sum of Average Bit Error Rate (ASABER) based MIMO precoding technique.

Security-aware dual-hop communication for amplify-and-forward relay networks

International Journal of Distributed Sensor Networks, 2019
The authentication scheme for vehicular ad hoc networks aims to improve the security and integrity of message delivery. The base station manages a large number of vehicular nodes, so the security communications are non-trivial.

Ergodic capacity of the exponentially correlated slotted amplify and forward relay channel

, 2012
In this paper we analyze the performance degradation of slotted amplify-and-forward protocol in wireless environments with high node density where the number of relays grows asymptotically large.

Performance Analysis of Cooperative Quadrature Spatial Modulation System With Hybrid Decode-Amplify-Forward Relaying Protocol

IEEE Access
This paper introduces the cooperative quadrature spatial modulation (CQSM) system with hybrid decode-amplify-forward (HDAF) relaying protocol. Compered with the traditional CQSM system which only uses amplify-and-forward (AF) protocol and decode-and ...

Joint Channel-Network Coding for the Gaussian Two-Way Two-Relay Network

EURASIP Journal on Wireless Communications and Networking, 2010
New aspects arise when generalizing two-way relay network with one relay to two-way relay network with multiple relays. To study the essential features of the two-way multiple-relay network, we focus on the case of two relays in our work.

Linear transceiver design for nonorthogonal amplify-and-forward protocol using a bit error rate criterion

, 2014
The ever growing demand of higher data rates can now be addressed by exploiting cooperative diversity. This form of diversity has become a fundamental technique for achieving spatial diversity by exploiting the presence of idle users in the network. This
