Abstract:In this paper, the multi-hop amplify-and-forward (AF) relaying transmission from the source to its destination after the m-th hop is considered, and the frame structure construction process of the hybrid time-switching (TS) and power-splitting (PS) simultaneous wireless information and power transfer (SWIPT) protocol is given. Under the constraint of the total transmission power and throughput of each relay, the trade-off relationship between power transmission efficiency and information transmission performance is evaluated. A non-closed formal expression of double hybrid parameters is derived, and the maximum number of achieved hops under a given node throughput is calculated. The numerical simulation results show that, in order to expand network coverage and ensure energy efficiency, the two parameters can be dynamically adjusted by different relay hops to achieve the optimal SWIPT performance.
