| 摘 要： | 混沌信号的类噪声特性使得对混有噪声的混沌信号处理相对困难.为此,对Farm er算法进行了改进,改进后的Farm er算法是在原Farm er算法的基础上优化结构,简化算法,提高噪声的衰减的有效性.通过对混有噪声的Henon序列进行仿真实验,仿真结果显示,改进后的Farm er算法能够提高噪声衰减的精度,降低与理想Henon序列的绝对误差.

| Abstract: | Noise-like characteristic of chaotic signals makes it very difficult to deal with chaotic signals with noise.Here the farmer algorithm is improved.The improved farmer algorithm optimizes the structure of original farmer algorithm,simplifying and improving the validity of noise attenuation.By comparison with the results of ideal Henon sequence mixed with noise,the improved Farmer algorithm is able to increase the precision of noise attenuation and reduce the absolute error between itself and ideal Henon sequence. |
