Exact Performance of Wireless-Powered Communications with Maximum Ratio Combining

We consider a single-antenna power transmitter (PT), a single-antenna information transmitter (IT) and a multiple-antenna information receiver (IR). The IT is autonomous without an energy source, and thus uses harvest-and-transmit protocol. It first harvests energy from the signals of the PT, and then uses all harvested energy for information transmission to the IR. For Nakagami-m fading channels, we analyze the system performance rigorously. In...
