摘要
Abstract
The signal of long wave communication was influenced by the atmospheric noise of the channel, which was non-Gausssian anc non-stationary typically, and conventional denoising method failed on it. In this paper, the method of median filter and wavelet threshold de-noising to suppress the VLF atmospheric noise was proposed. The SNR improvement factor was chosen as the indication of the performance improvement, and the simulation was implemented on Matlab platform. The simulation result of this method shown that the new approacr could remove VLF channal noises effectively and improve the system performance.关键词
