摘要: Abstract In this paper, we investigate the impact of correlated channels on wireless powered cooperative networks, where direct links between source and destination exist are with relaying links. considered system, time switching-based protocol simultaneous information power transfer is used. order to enhance system performance, a better branch link selected. We evaluate transmission performance by deriving closed-form expression outage probability as well asymptotic results for proposed scheme, in high regime transmit power. Based theoretical analysis, effects parameters, such channel correlation coefficient, average fading power, energy harvesting coefficient slot allocation probability. Numerical provided verify analysis.
