On the Performance of PDMA With Decode-and-Forward Relaying in Downlink Network

the effect of task cognitive complexity and time limit on the performance of the learners with different proficiency levels in second language writing skill

this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...

On Throughput Performance of Decode and Forward Cooperative Relaying with Packet Combining and Arq

Cooperative Diversity can be used by wireless nodes to take the benefit of broadcast nature and inherent spatial diversity of wireless channel to relay messages for each others. This helps to propagate redundant signals over multiple paths, which can be used to combat the channel noise and fading effects. We investigate the use of packet combining in cooperative diversity scenario. In our appro...

Performance Evaluation of Decode-and-Forward Relaying for Cellular Communication Network

In this paper, the performance of decode –and-forward relaying over multiple fading channels is been analyzed. Here at first overviewed traditional relaying techniques and compared it with coded cooperative relaying. BER performance the different schemes are analyzed and the results shows that coded cooperative relaying give better performance in terms of BER analysis. A new technique called ne...

Decode-and-forward relaying based on orthogonal complementary codes

In this note, we propose a full-duplex decode-and-forward cooperative diversity scheme based on code division with orthogonal complementary codes. We consider a simple case in which a single user is assisted by a single relay to achieve cooperative diversity. When the cooperation is full-duplex, the operational delay of the relay makes the channel asynchronous and this may cause multiple-access...
