Abstract
To improve the anti-jamming capability and the spectrum efficiency in wireless communication links with high-moving targets, an adaptive beamforming (BF) technique based on antenna array is proposed for FH systems in this paper (i.e., FH-BF systems). A modified FH-BF receiver structure based on uniform circle array (UCA) is designed so as to reduce the steering-vector fluctuation and to improve the convergence rate. The performance of the proposed system, i.e., bit-error-rate (BER), output signal-to-interference-and-noise (SINR) and convergence rate of the adaptive BF, are fully investigated under a serious jamming attack. The simulation results show that the proposed FH-BF system with $M$-ary FSK signal converges in a reasonably low number of snapshots, which implies that the beamformer can quickly keep up with the position change of high-speed jammers. In addition, the proposed system can significantly offer the additional SINR gains, and improve the anti-jamming capability without any extra cost of bandwidth.
