摘　　要：针对传统全频道干扰需利用单一频道干扰机进行相对费时的频道跳转,提出了一种全频道IEEE 802.11g干扰机(ARJ),ARJ利用临频干扰,尤其是非交叠信道临频干扰实现对全频道的覆盖.与单一频道干扰机相比,ARJ在一个固定频道上便可实现全频道干扰,可调节干扰信号发射功率实现可变的干扰半径,通过设置干扰频度达到能量有效.引入信道比特错误率的DCF马尔可夫链模型的理论分析和模拟场景的仿真实验表明:ARJ可以实现对IEEE 802.11g全频道的干扰,其在真实实验中得到实现和验证.In all-channel jamming,traditional single channel Jammer needed relative time consuming channel switching.In this paper,an IEEE 802.11g all-channel Jammer（ARJ） by adjacent channel interference（ACI）,especially non-overlapping channel interference is proposed.Compared with single channel Jammer,ARJ has the advantages of realizing all-channel jamming on fixed single channel,realizing alterable jamming radius by adjusting transmission power of jamming signal and realizing energy-efficient jamming by adjusting jamming frequency.Through theoretical analysis by the Markov chain model of DCF under the channel bit error rate（BER） and simulation scenario experiments,it is found that ARJ can jam all channels of IEEE 802.11g.Moreover ARJ is also implemented and verified in the real experiments.
