  We demonstrate a frequency synchronization scheme with the phase noise
compensation function placed at the client site. One transmitting module hence
can be linked with multiple client sites. As a performance test, using two
separate 50 km fiber spools, we recover the 100 MHz disseminated reference
frequencies at two remote sites, separately. Relative frequency stabilities
between two recovered frequency signals of 2.8E-14/s and 2.5E-17/day are
obtained. This scalable scheme is suitable for the applications of frequency
dissemination with a star-topology, such as SKA and DSN.
