摘要
从大气噪声产生的原因入手,在分析大气噪声特性的基础上,综述了脉冲噪声抑制的一般方法、中值滤波与小波分析联合降噪处理方法和非线性自适应处理方法,指出了不同方法应用于潜艇甚低频通信大气噪声抑制时的优缺点,通过分析认为采用适当的信号处理技术能够有效提高潜艇甚低频通信系统性能。
Commence from the reason of atmosphere noise creation, on the foundation of analytical atmosphere noise characteristic, the general method of impulsive noise control, median filter and wavelet analysis treatment method of unite control noise and nonlinear adaptive processing method are presented, and the advantages and disadvantages about different methods for applying sub-marine VLF communication atmospheric noise control are pointed out. The analysis proves that appropriate signal processing technology can effectively improve the performance of submarine VLF communication system.
