چکیده
In this paper, an adaptive relay scheme based on post SNR in cooperative communication system is proposed. conventional cooperative scheme has used the same modulation at a relay. The proposed scheme uses hierarchical modulation at the source and adaptive transmission based on the post signal to noise ratio (SNR) at a relay. Accordingly, the symbol error rate (SER) and throughput performances are improved by the proposed scheme.

Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
متن کاملPerformance Study of Untrusted Relay Network Utilizing Cooperative Jammer
Abstract—In this paper, the problem of secure transmission in two-hop amplify-and-forward (AF) systems with an untrusted relay is investigated. To prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the destination-based cooperative jamming (DBCJ) technique is used. In this method the destination sends an intended jamming signal to the relay. T...

متن کاملPower Allocation In Cooperative Relay Channels
This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...
متن کاملSum-Rate Maximization Based on Power Constraints for Cooperative AF Relay Networks
In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...
