Effective capacity maximization of two-way full-duplex and half-duplex relays with finite block length packets transmission

In order to satisfy the delay requirements of telecommunication systems, in this paper, we present a cooperative network with short packet transmission Rayleigh fading channel. The desired relay can be implemented as two-way half-duplex (HD) or full-duplex (FD). Also, for more accurate satisfaction and reduction communication delays, sending receiving packets is considered. Effective capacity appropriately measures rate under constraint. Therefore, it considered performance evaluation criterion here. With relay, two nodes exchange data each other using simultaneously. priorities are not necessarily same. increase performance, system modeled solved multi-objective problem. way, available power divided between nodes, effective maximized. Depending on different conditions, optimal amount allocated calculated. However, due complexity time consuming calculations, an approximate method which speeds up calculation presented. approximated solution has very close power. Finally, various comparisons have been made conditions HD FD relays. improvement allocation shown, especially when located middle nodes.
