摘要：
We consider a two-hop decode-and-forward relay system with wireless powered source node. Source and destination are in the coverage range of the relay and direct link connecting them is assumed to be blocked. The signal transmitted by the relay node is used to harvest energy at the source and forward data to the destination in even time slot. In the following odd slot the energy harvested at source is used to communicate data to relay node. The cycle continues and the source data is communicated to the blocked destination node. The average symbol error rate (SER) of the system is analyzed for Rayleigh faded links when data is i) M-ary phase-shift keying modulated with coherent detection and ii) orthogonal M-ary frequency-shift keying modulated with non-coherent detection. The high signal-to-noise ratio approximations of the average SER are also obtained to investigate the effects of modulation order and relay placement on the system's performance.
