双极性脉冲调制的抗脉冲干扰解调
Demodulation for Bipolar Pulse Modulation under Pulse Interference
摘要:
空间电磁环境日趋复杂，各种干扰不可回避，促使了抗干扰技术的发展。针对双极性脉冲调制体制，本文主要利用各种滤波算法来削弱脉冲干扰对调制信号的影响，进一步优化信号波形，提取波形特征，最终利用SVM分类算法进行判决解调，明显提升了解调性能。
Abstract:
Space electromagnetic environment is increasingly complex; all kinds of interference cannot be avoided, to promote the development of anti-jamming technology. For the bipolar pulse modula-tion system, this paper mainly uses various filtering algorithms to weaken the influence of pulse interference on the modulation signal, further optimizes the signal waveform, extracts the wave-form characteristics, and finally uses SVM classification algorithm for demodulation, significantly improving the demodulation performance.
