Abstract : We consider a single-input-multiple-output (SIMO) system where power radiated from the transmitter is received and harvested at the receiver. In the proposed algorithm, we study the influence of Channel State Information (CSI) on the maximum harvestable power at the receiver along with the optimization of receiver architecture, adaptive transmit beam forming, and receiver operation policy. On keen observation of the output response, our simulations results show that adaptive transmit beam forming with optimal time allocation for channel estimation will be favourable for maximization of harvested energy.
