摘要
研究了关联维数的计算 ,对于周期信号上叠加微弱信号的情况 ,采用小波分解的方法 ,计算关联维数 。
A new method is provided to prompt the accuracy of correlation dimension of weak signal in strong periodic signal. For two kinds of signals, correlation dimension is calculated with former and hyadic wavelet method. The result shows that the new method is effective.
