The power allocation problem in a hybrid system with power grid and energy harvesting is investigated to maximize system throughput. From the power grid, peak power constraints and the total energy budget constraint are considered. Water-Filling has been used as a fundamental algorithm to solve the target problem. We proposed the optimal power allocation solution by first applying water-filling to...
A large scale MIMO (multiple-input multiple-output) system with cloud base-station (BS) architecture is proposed to address the lack of spectrum resource. Potential transmission schemes including uplink training and downlink precoding are described and analyzed in this paper. The novel system is designed to mitigate interferences among users and make full use of spatial multiplexing gain. Simulation...
