摘要
讨论了多重分形在时间序列分析中的应用,并分别针对一些噪声序列、受干扰信号序列,计算了其多重分形广义维数,试图探索一种新的方法,为时间序列的分析提供新的依据.在信号处理中,尤其在雷达信号处理中有很好的应用前景.
Multi-fractal is introduced to the field of time series research. To get more information,fractal dimensions of some noise series, disturbed signal series and 1/f fractal signal are computed according to multifractal method. Some good practical prospects are obtained in signal processing by this method, especially in radar signal processing and some given experimental results.
