Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
An algorithm to automatically recognize interferences is proposed to solve the problem that we can´t take the right interference suppression method to improve the performance of direct sequence spread spectrum (DSSS) communication system because of the unknown interference types. First, the mathematical models of 8 types of important interferences in DSSS system are described; Then, the features of interferences from time domain, frequency domain and time-frequency domain are extracted; And finally, a five-order automatic interference recognizer based on decision tree support vector machine is constructed, and the automatic recognition of the interferences is realized. Simulation results demonstrate that the proposed algorithm provides a very high recognition rate when ISR is not lower than 9dB.
