This letter introduces a novel wireless-powered backscatter communication\nsystem which allows sensors to utilize RF signals transmitted from a dedicated\nRF energy source to transmit data. In the proposed system, when the RF energy\nsource transmits RF signals, the sensors are able to backscatter the RF signals\nto transmit date to the gateway and/or harvest energy from the RF signals for\ntheir operations. By integrating backscattering and energy harvesting\ntechniques, we can optimize the network throughput of the system. In\nparticular, we first formulate the time scheduling problem for the system, and\nthen propose an optimal solution using convex optimization to maximize the\noverall network throughput. Numerical results show a significant throughput\ngain achieved by our proposed design over two other baseline schemes.\n
