摘要

本文比较研究了各种信号建模技术，结合幂级数展开设计了基于分数阶积分的无限脉冲响应(IIR)滤波器，用于1/fβ序列合成。结果表明，功率谱的近似精度、计算时间和所需的空间存储在很大程度上取决于所采用的信号建模技术。采用迭代法得到了最好的结果。通过引入基于脉冲不变性的方法，降低了对时间和空间存储的负担。

On the use of signal modelling techniques for simulating 1/ fβ -noise

This paper presents a comparison study between various signal modeling techniques, combined with power series expansion to design infinite impulse response (IIR) filters based on fractional integration for 1/fβ sequences synthesis. It was found that the approximation accuracy of the power spectra, the computation time and the space memory required depend highly on the signal modeling techniques used. Best results were obtained using iterative technique. The burden of time consumption and space memory required are lowered by introducing impulse invariance based method.
