为了减小交叉干扰对罗兰C数据链应用与定位应用的影响,文中设计了一种数据链交叉干扰抑制新方法对信号进行滤波处理,通过仿真和实测数据的验证,该方法获得了较好交叉干扰抑制效果,并大大提高了罗兰C数据链PPM解调正确率。

英文摘要：

In order to alleviate the interference of CRI to the application of Loran C datalink and positioning, a new CRI suppression algo- rithm in datalink usage was designed for processing the signal. Through validation of simulation data and real data, this algorithm achieved preferable CRI suppression effect, and enhanced correctness of PPM demodulation in Loran C datalink.
