提出一种基于信道质量优化的动态频谱抗干扰技术。通过对信道历史相关参数的估计，建立信道质量优化准则，而后按照准则进行频谱感知和频谱预测，并将两者频谱决策结果进行融合，当频谱决策结果为空闲(即无干扰或者信道空闲)时，用户可动态地接入该信道进行数据传输。通过仿真表明，在相同呼叫次数的情况下，可成功动态地躲避对方的干扰，加快通信链路成功建立平均时间。

A dynamic spectrum anti-jamming technology based on channel quality optimization is proposed. Firstly, the historical related parameters of channel are estimated and the rule of the channel quality optimization is established based on above parameters. Then, spectrum prediction and spectrum sensing are conducted based on the rules and the decision fusion is further made. Only when the result of spectrum decision is idle(no jamming or the channel is idle), the user can access the channel to transmit data. Simulation results show that this algorithm can both avoid the communication interference and reduce the average linking time of establishing links successfully.
