    LOW COST IMPLEMENTATION FOR SYNCHRONIZATION IN DISTRIBUTED MULTI ANTENNA USING USRP/GNU-RADIO

    Carrier Frequency Offset Synchronization is play a very important rule in the Distributed Multi antenna system, since the system has different individual clock instead of common clock as in the centralized multi Antenna system. One of the established synchronization methode for different transmitter devices is Costas Loop. Some implementation of the synchronization for distributed multi antenna is discussed in some research works. In this paper we propose the low cost implementation of synchronization in distributed multi antenna and more simplified measurement method of synchronization in distributed multi antenna. The measurement result showed that the syncronization can compensate 0.5 kHz frequency offset experienced by the transmitters in the Distributed Multi antenna system
