| 摘 要： | 本文着眼干信号的非线性性质,把分形理论引入信号检测,针对FSK信号(铁路移频信号)检测的特点,提出通过计算相关维数做为FSK信号的分形维数的检测方法.本文还用此方法对仿真FSK信号和实际采集的FSK信号做了模拟检测,实验结果表明此方法可以在较强噪声背景下检测出更多低频FSK信号.

| Abstract: | In this paper, based on fractal and chaos theory, we propose a method that bv comouting and extractina fractal dimension to be close to relation dimension, we can succeed detect simulating sianal and real signal. The results indicated that this kind of filter benefited our detecting more slow SNR signals. |
