A closed-loop deterministic phase synchronization algorithm for distributed beamforming
Ranjie Hu, Li Guo, Chao Zhang, Jiaru Lin · 2014
Distributed beamforming (DBF) is a cooperative technology that several nodes transmit a common message to a receiver efficiently. The key to DBF is to ensure every node's signal adds coherently at the receiver by synchronizing node's carrier phase. In this paper, we present a closed-loop deterministic phase synchronization algorithm in order to pursue less synchronization time, less feedback information, less energy consumption. We analyze the performance of this algorithm and make a comparison between the new and the previous closed-loop phase synchronization algorithms.
