A DF performance analysis in half-duplex and full-duplex relaying network

Abstract

Energy harvesting (EH) protocol relied on the surrounding wireless communication technology, has recently made the development approach to enlarge the existing time of the radio systems. The energy harvesting structure for the half duplex and full duplex relaying systems is investigated. By using time switching based relaying (TSR) protocol and the Decode-and-Forward (DF) scheme, we infer the approximated clause of the outage probability and then calculate the throughput of the half-duplex and full-duplex system. An essential outcome can be shown clearly that the position of relaying, the achievement rate, the noise at the source and relay as well as the energy conversion factor in TSR, effect on their outage probability and throughput. Ultimately, comparing the performances of the full- duplex (FD) and half-duplex (HD) relaying architectures, our taken results illustrate that, for a normal optimal networks, sometimes, HD model is better than FD one and contrariwise such as the relay position is near the transmitter, HD outage probability is better than FD. When increases η, the HD throughput gets well etc. Hence, depending on real condition, we use conformably what model is beter.
