  Abstract

In military environment, wireless communication systems does not guarantee reliability due to the effect of interference by a jamming attack. To reduce the influence of the jamming attack, transmitter sends identical signal in some slots by using Frequency Hopping Spread Spectrum(FHSS) and receiver combines that received slots. This paper proposes the Cell Average Constant False Alarm Rate(CA-CFAR) detection algorithm to remove the received slot attacked by the jammer, and utilizes the selection-combining technique to increase array gain. Computer simulation demonstrates jamming detection performance as a function of the false alarm rate and jammer bandwidth for the FHSS, and shows Bit Error Rate(BER) performance as a function of the ratio of bit energy(Eb) to the power spectral density(J0 ). Computer simulation proves the proposed method exhibits better BER performance than the conventional combining method.
