摘要
为提升通信抗压制干扰能力,提出了一种基于误比特率(BER)优化的干扰调制抗干扰通信方法。首先,构建干扰调制抗干扰的系统模型,发送端利用可编程增益放大器(PGA)调制转发干扰信号,通过放大器不同模式的增益控制传输不同信息。其次,以最小化BER为目标,推导能量检测器最佳判决门限,并给出基于最优BER的干扰调制抗干扰通信方法。最后,为降低方法实现复杂度,提出了一种基于BER近似的低复杂度干扰调制抗干扰通信方法,在保证BER性能的同时显著降低计算开销。仿真结果表明,所提方法的BER性能优于传统干扰调制抗干扰方法,具备很强的抗压制干扰能力。
To enhance the communication’s anti-suppressive jamming capability,a jamming modulation aided antijamming communication method based on optimized bit error ratio(BER)was proposed.Firstly,the system model of jamming modulation aided anti-jamming was constructed,where the transmitter utilized a programmable gain amplifier(PGA)to modulate and forward the jamming signal.Different gain control modes of the PGA were utilized to transmit distinct information bits.Secondly,aiming to minimize the BER,the optimal decision threshold for the energy detector was derived,and a jamming modulation aided anti-jamming communication method based on optimal BER was provided.Finally,to reduce the implementation complexity of the method,a BER approximation based on low-complexity jamming modulation aided anti-jamming communication method was proposed,which significantly reduced computational overhead while maintaining BER performance.Simulation results demonstrate that the proposed method presents superior BER performance compared to the traditional jamming modulation aided anti-jamming methods and exhibits strong resilience anti-suppressive jamming.
