| Energy Harvesting Wireless Communications With Energy Cooperation Between
Transmitter and Receiver |
Energy harvesting is an increasingly attractive source of power for wireless communications devices. In this paper, we consider a point-to-point (P2P) wireless communications system,
where both the practical transmitter and receiver, whose hardware circuits consume non-zero power when active, are powered solely by the energy harvested from external sources. An energy cooperation save-then-transmit (EC-ST) scheme is proposed: both the transmitter and receiver go into sleep mode to save energy for a proportion of time while their passive energy harvester units collect energy for later operations, and then become active to communicate for the remaining time proportion (referred to as the active-ratio), during which energy is allowed to flow between the transmitter and receiver.We first consider additive white Gaussian noise one-way channels with two-way energy transfer under a deterministic energy arrival rate. In this case, the optimal activeratio and the energy cooperation power are obtained in closed form to achieve the maximum throughput. Next, for Rayleigh block fading channels with a stochastic energy arrival rate, we find the optimal energy cooperation power for minimizing the outage probability. Finally, numerical and simulation results are presented to validate the analytical findings. |

| CE1 | Speaker Verification Method for Operation System of Consumer Electronic Devices | A system is proposed that can remotely operate consumer electronic devices by voice. It uses the mobile phone as a controller. And it uses the CELP(code excited linear prediction) parameters that are used for speech coding in
mobile phones. A speaker verification function protects private information and separates the user’s voice from that of people nearby who are also speaking. A CELP-based speaker verification method is used to match the audio stream by comparing the trajectories of continuous phonemes. Experimental evaluation of the speaker verification method demonstrated the effectiveness of the proposed verification method |
