Satellite communication anti-jamming methods at present are mostly based on spread spectrum and filtering technology. There is defects for these methods on the performance of spectrum efficiency and anti-jamming. In this paper, we investigated the separation of communication signal and jamming signal to obtain communication anti-jamming. In the proposed method, only the independency characteristic between the communication signal and the jamming signal is used. The separation problem is essentially a multi-parameter joint optimization problem, and there is no analytical solution. This paper uses an artificial bee colony optimization algorithm to solve the blind separation problem and obtains a sub-optimal solution.
