We reconstructed the phase space and calculated the nonlinear parameters such as correlation dimension, the largest lyapunov exponent, approximate entropy, and l - z complexity of the data. it can be conclud from the results that the reconstruction of heart beat rate signal is strange, its correlation dimension is between 5 to 7 and have the character of fractal dimension, its largest lyapunov exponent is larger than zero, its approximate entropy and l - z complexity are obviously differ from noise. we can draw a conclusion from all above : the heart beat rate signal is n ' t simple noise, it is high dimensional chaos obeys certain dynamical law
我們還對信號進行了相空間重構,計算了信號的關聯維數、最大lyapunov指數、近似熵和復雜度這幾個非線性特徵量,我們發現,心率信號的吸引子是奇怪吸引子,關聯維數介於5到7之間,具有分維的特徵,其最大lyapunov指數大於0 ,其近似熵值和復雜度值明顯區別于噪聲,這說明心率信號不是隨機噪聲,它是服從確定性動力學規律的高維混沌信號。
