In this letter we are concerned with the problem of link scheduling for throughput maximization in wireless networks that employ a cooperative amplify and forward (AF) protocol. To address this problem first we define the signal-to-interference plus noise ratio (SINR) expression for the complete cooperative AF-based transmission. Next, we formulate the problem of link scheduling as a mixed inte...

Rayleigh fading channels is theoretically derived. Numerical results validate our theoretical analysis and show that by introducing overhearing among relays, the outage performance of the system can be greatly improved. It also shows that there is a trade-off between system sum outage capacity and the transmitted number of symbols.

Quadrature spatial modulation (QSM) is a recent digital multiple-input multiple-output (MIMO) transmission technique. Combined with cooperative relaying, QSM improves the overall spectral efficiency and enhances the communication reliability. In this paper, we study the performance of QSM amplify-and forward cooperative relaying systems. In particular, a closed-form expression for the average p...

This paper provides a general analysis of cooperative amplify-and-forward relay networks and gives a unified and comparative view of various proposed systems. The studied cooperative relay networks offer spatial diversity gains that conventional multi-antenna systems often fail to achieve due to limitations of the feasible number of antennas per terminal and correlated propagation. We first pre...
