Methods for Carrier Synchronization of Distributed Transmit Beamforming
摘要
Abstract
Distributed transmit beamforming is a form of cooperative communication in which two or more information sources simultaneously transmit a common message and control the phase of their transmissions so that the signals combine at an intended destination . Carrier frequency offset will significantly degrade the performance of communication by damaging the combine at the destination . It proved that the carrier synchronization is the significant problem for distributed transmit beamforming and introduced some existing methods for carrier synchronization of distributed transmit beamforming that can reduce the effect of the carrier. One approach to frequency synchronization is to employ a master-slave architecture . There are two basic approaches to phase synchronization, closed-loop phase synchronization and open-loop phase synchronization. After distributed carrier synchronization, the transmissions combine constructively at the destination. That makes the feasibility of distributed transmit beamforming increases.关键词
