英文摘要	Recently, some theoretical models predicted that a small fraction of fast radio bursts (FRBs) could be associated with gravitational waves (GWs). In this Letter, we discuss the possibility of using GW/FRB association systems, if they are commonly detected in the future, as a complementary cosmic probe. We propose that upgraded standard sirens can be constructed from the joint measurements of luminosity distances D-L derived from GWs and dispersion measures DMIGM derived from FRBs (i.e., the combination D-L . DMIGM). Moreover, unlike the traditional standard-siren approach (i.e., the D-L method) and the DMIGM method that rely on the optimization of the Hubble constant H-0, this D-L. DMIGM method has the advantage of being independent of H-0. Through Monte Carlo simulations, we prove that the D-L . DMIGM method is more effective for constraining cosmological parameters than D-L or DMIGM separately, and that it enables us to achieve accurate multimessenger cosmology from approximately 100 GW/FRB systems. Additionally, even if GW/FRB associations do not exist, the methodology developed here can still be applied to those GWs and FRBs that occur at the same redshifts.
