| Abstract: | As the main noise source interfering with low frequency signal, the gaussization method of atmospheric noisewas studied in this paper, and a new noise gaussization method based on the fast solving algorithm of new chaotic equationand the chaotic phase transformation discriminant algorithm were proposed. Based on the non-linear signal processingtechnology, the chaotic gaussization of low frequency weak signal was completed by simulating the channel environment inthe laboratory. The theoretical experiment of 2PSK weak signal verifies its validity, which can provide a basis for the devel?opment of low frequency receiving technology. |
