说明：  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。(Aiming at the problem of anti-jamming and interference suppression in wireless communication, a method of anti-jamming in polarization domain is proposed. The oblique projection polarization filter is used in the signal polarization domain to overcome the shortcomings of the traditional frequency domain anti-jamming technology. By studying the characteristics of oblique projection filter, we design a variety of interference suppression and anti-interference technologies in signal polarization domain, including optimizing the statistical characteristics of polarized emission signal, augmented oblique projection filter based on non-linear vector transformation and received signal, in order to improve the design of oblique projection filter.)
