Capacity analysis of the successive AF relaying aided cooperative DS-CDMA uplink [PDF]
, 2012 An amplify-and-forward (AF) based successive relaying aided network (SRAN) is designed for a multi-user spread-spectrum scenario conceived for noncoherent (NC) detection in order to convert the typical 50% half-duplex relaying-induced throughput loss to ...

Simultaneous Wireless Information and Power Transfer for Cooperative Relay Networks With Battery
IEEE Access, 2017 In this paper, we investigate simultaneous wireless information and power transfer in a cooperative communication network consisting of one source, one battery-enabled relay, and one destination node. An amplify-and-forward relaying method is considered,

Energy Efficiency Analysis in Amplify-And-Forward and Decode-And-Forward Cooperative Networks [PDF]
2010 IEEE Wireless Communication and Networking Conference, 2010 In this paper, we have studied the energy efficiency of cooperative networks operating in either the fixed Amplifyand- Forward (AF) or the selective Decode-and-Forward (DF) mode. We consider the optimization of the M-ary quadrature amplitude modulation (MQAM) constellation size to minimize the bit energy consumption under given bit error rate (BER ...

Sequential slotted amplify-and-forward with partial relay isolation [PDF]
, 2012 In this paper, we propose a novel relay ordering and scheduling strategy for the sequential slotted amplify-and-forward (SAF) protocol and evaluate its performance in terms of diversity-multiplexing trade-off (DMT).

Full Duplex AF and DF Relaying Under Channel Estimation Errors for V2V Communications
IEEE Access, 2018 In this paper, we investigate the outage performance of full-duplex (FD) and half-duplex (HD) vehicle to vehicle (V2V) networks. We consider two vehicular communication scenarios with the assistance of roadside unit (RSU), i.e., RSU-to-vehicle-to-vehicle
