Abstract: To overcome the effects of the intense jam for the full duplex (FD) systems in the extreme spectrum environment, this paper proposed a novel Digital Self-Interference Cancellation (DSIC) method that adapts to the frequency agility full duplex systems. The error compensation model of the full working band was calculated offline and could generate the self-interference (SI) channel coefficients real-timely to reconstruct the SI signal and accomplish the DSIC. The numerical simulation results indicate that the level of the residual SI signal after the DSIC is below the noise floor level in the full band, which also demonstrate the consistency and convergence of the proposed method at different frequency points.
