| 1. | One is the bss based on kernel density estimation ( kde ) and genetic algorithm ( ga ) , the other is the blind deconvolution based on high order cross cumulants and ga . without nlf , the performance of separation in both algorithms is independent with the kurtosis of the sources
两种算法的实现无需引入非线性函数,因此都与源信号的峭度性质无关;另外,选取全局搜索的遗传算法进行寻优,避免了梯度法搜索的局部性,使得算法均能收敛到问题的全局最优解。 |
