摘要: In this paper, we propose and analyze a simple protocol that simultaneously exploits two potentials offered by wireless relay systems: diversity gains pathloss savings. An intermediate decode-and-forward assists transmission from source to destination, the destination combines signals it receives relay. The key feature of proposed system is node decides independently whether or not forward information thereby minimizing risk error propagation while providing truly constructive gains. combination with savings, leads significant over both direct conventional relaying. results are obtained an analysis end-to-end bit rate, which confirmed simulation.
