摘要: 针对无线通信中的抗干扰和干扰抑制问题,提出一种极化域通信抗干扰方法。在信号极化域利用斜投影极化滤波器,以克服传统的频域抗干扰技术的缺点。通过对斜投影滤波器的特点进行研究,在信号极化域设计多种干扰抑制和抗干扰技术,包括优化极化发射信号、非线性矢量变换的增广斜投影滤波器以及接收信号的统计特性,以改进斜投影滤波器的设计。仿真结果证明,与传统斜投影滤波器抗干扰方法相比,该方法的抗干扰性能以及干扰抑制能力更优。

Abstract: Aiming at the anti-jamming and interference suppression in wireless communication,this paper proposes a communication anti-jamming method in polarization domain.It uses oblique projection polarization filter in the signal polarization domain to overcome the shortcomings of the traditional anti-jamming technology in frequency domain.Through the research on the characteristics of oblique projection filters,a variety of interference suppression and anti-jamming techniques are designed in the signal polarization domain,including the optimization of polarized transmit signals,the augmented oblique projection filter of nonlinear vector transform,and the statistics of received signals,to improve the design of oblique projection filter.Simulation results show that,compared with the traditional anti-jamming method with oblique projection filter,the proposed method has better anti-jamming performance and interference suppression performance.

Key words: polarization domain, anti-jamming, enhanced oblique projection filter, non-linear vector translation, polarization emission optimization, random polarization wave
