Abstract
It is known that the sign problem emerges as a complex phase of the canonical partition function in canonical approach. We confirmed that the origin of the complex phase is breaking of the charge conjugation with a simple model. The main purpose of this study is suppressing the complex phase even at low temperature. We realized it by increasing the number of gauge field configurations. In particular, the complex phase was suppressed less than $\pi/2$ in $1\sigma$ for $N_B<7$ at $T=0.81T_c$
