To make full use of the population's global statistics information, this paper introduced estimation of distribution algorithm into binary artificial bee colony algorithm, and proposed a binary artificial bee colony algorithm based on estimation of distribution algorithm. It guided the candidate solution by the global statistics information from the estimation of distribution algorithm, which could enhance the global exploration ability. It designed the multidimensional update strategy in the discrete domain, which quickens convergence speed and reduces the computational complexity. The simulation results show that, compared with the traditional binary artificial bee colony algorithm, the performances of the improved algorithm are better in the optimization accuracy, convergence speed and robustness.

This paper proposed a novel blind deconvolution algorithm based on PSO to remove the convolution effect for sound signals in communication channel. It used the temporal predictability as the measure of deconvolution and used PSO for optimizing the cost function based on it. Then, the filter coefficient for deconvolution could be got and the signals could be deconvoluted successfully. Simulation results show that the deconvolution property of the algorithm for sound signals is good. The values of correlation coefficient and signal-to-noise ratio between recovered signals and source signals are all high. [ABSTRACT FROM AUTHOR]
