摘要
通过针对二相相移键控(BPSK,Binary Phase Shift Keying)最佳干扰样式的研究,从理论上分析了载波环路的特点。根据载波环路的收敛特性提出了窄带噪声调相干扰样式,该调制样式能够破坏载波环路锁相环的收敛特性,使解调的误码率增高。通过加载几种不同干扰信号的实验,证明了针对载波环路的干扰要比常规的干扰方式更高效。得出了使用窄带噪声调相信号作为干扰源是BPSK调制信号的最佳干扰样式,可以进一步地节省干扰功率,提高干扰效率。
Based on study of optimum jamming of BPSK (Binary Phase Shift Keying), the theorectical analysis of carrier loop characteristic is done, and in accordance with the convergence feature of carrier loop, the noise-phase-modulation jamming mode is proposed. This jamming mode can destroy the carrier loop and increase the bit error ratio. Experiment indicates that this jamming carrier loop is better than the traditional jamming mode, the noise-phase modulation is the optimum jamming mode for psk modulation, and this jamming mode can effectively save jamming power and raise jamming efficiency.
