A reference-free radiation interference cancellation method

According to the characteristics of radiation interference with communication among modern warships, this paper has proposed a reference-free radiation interference cancellation method to deal with radio communication jamming in a limited space. The method can be adopted to make a proper improvement of the existing LMS algorithm aimed at short-wave radiation interference by use of priori information of useful signal and interfering signals, so that the radiation interference with the radio communication system can be reduced significantly and meanwhile the dependence on the information of interference source can be eliminated. The simulation results show that the method is effective, which may provide a new way of designing the cancellation.
