Abstract

© 2016 IEEE. This paper analyzes the performance of a multiple-antenna access point (AP) system with an energy-constrained single-antenna destination node in various Bernoulli-Gaussian impulsive noise environments. More specifically, we deploy the harvest-then-transmit protocol where communication is accomplished over two distinct phases: i) power transfer phase (downlink), ii) information transmission phase (up-link). In this respect, an analytical expression for the ergodic outage probability is derived and validated with Monte Carlo simulations. Results have shown that increasing the source transmit power or/and the number of AP antennas will minimize the ergodic outage probability. It is also presented that careful selection of the energy harvesting time is important to enhance the system performance.
