Covariance-based follower jamming blocking algorithm for slow FH-BFSK systems

In this paper, a covariance-based algorithm with multiple antennas is proposed to eliminate the follower jamming for frequency hopping systems (FH) by finding the interference-blocking filter over quasi-static flat fading channels. The system uses the auto-covariance matrix of the received signal and M-array receive antennas. The simulation results show that the proposed approach can estimate the interference-blocking filter regardless of the jamming strength, which is especially available in the case that the follower jamming is much stronger than the FH signals.
