A repeating fast radio burst (FRB), FRB 20180916B (hereafter FRB 180916), wasreported to have a 16.35-day period. This period might be related to aprecession period. In this paper, we investigate two precession models toexplain the periodic activity of FRB 180916. In both models, the radio emissionof FRB 180916 is produced by a precessing jet. For the first disk-driven jetprecession model, an extremely low viscous parameter (i.e., the dimensionlessviscosity parameter $\alpha \lesssim 10^{-8}$) is required to explain theprecession of FRB 180916, which implies its implausibility. For the secondtidal force-driven jet precession model, we consider a compact binary consistsof a neutron star/black hole and a white dwarf; the white dwarf fills its Rochelobe and mass transfer occurs. Due to the misalignment between the disk andorbital plane, the tidal force of the white dwarf can drive jet precession. Weshow that the relevant precession periods are several days to hundreds of days,depending on the specific accretion rates and component masses. The duration ofFRB 180916 generation in the binary with extremely high accretion rate will beseveral thousand years.
