GSM系统上行控制信道干扰方法研究

摘要

GSM对抗在军事和反恐行动中得到了越来越多的重视，由于对上行信道干扰对干扰机的发射功率要求更低，更易于实现，国内外对GSM对抗技术的研究主要集中于如何对其上行信道进行干扰。在分析GSM系统上行控制信道结构的基础上，仿真了连续时间干扰和周期脉冲序列干扰样式的效果及其影响因素，设计了GSM系统上行控制信道最佳干扰波形，提出了一种周期序列脉冲干扰方案，并通过仿真，研究了该方案的可行性和干扰效能。%GSM countermeasure is increasingly concerned in military and counter⁃terrorist operations. Since jamming uplink requires lower transmission power of the jammer and is easy to realize,the researches of GSM countermeasure technology at home and abroad mainly focus on how to interfere the uplink. Based on the analysis of the uplink control channel structure,the effects and influential factors of serial interference and periodic impulse sequence interference modes are simulated in this pa⁃per. The most effective waveform to interfere GSM system uplink control channel is designed and a periodic⁃sequence pulse inter⁃ference solution is proposed in this paper. Through simulation,the feasibility and interference effectiveness of the solution is re⁃searched.
