摘要：
A novel blind signal separation algorithm based on bacterial foraging optimization was proposed. Fourth-order cumulant of signal was used as objective function for separation and Givens transform method was used for reducing the number of variables in objective function. The bacterial foraging optimization algorithm was used for optimizing the objective function transformed and source signal could be separated from mixed signal. Simulation results show that the separation algorithm based on bacterial foraging optimization can achieve the blind separation successfully and the separation precision is high.
