摘　　要：为了解决传统通信信道的传输精度低、干扰功率大的问题,提出一种高容量保密通信信道的协同干扰功率分配方法。首先构建高容量保密通信框架,并分析信道数据特征,为后续计算提供运作平台;其次把通信的有效干扰区域叠加,将多目标干扰区域整合为单个干扰区域,使用整数规划手段建立协同干扰功率分配模型,以此判断袭击目标的干扰程度,做出相应反干扰防范措施;最后利用基于自适应分布的协同干扰功率分配方法,在高容量保密通信总功率收敛状态下,运用速度最大化原则推算信道开关的阈值,使用最小均方偏差准则实现自适应分步功率分配,降低信道传输误码率,保证通信数据的正确。仿真结果表明,提出的方法可以降低干扰功率,并保证信道数据高精度传输,大幅度提升通信信道的抗干扰能力,拥有较好的鲁棒性。In order to improve the transmission accuracy and reduce interference power of communication channel,this paper proposed a method of cooperative interference power allocation in high-capacity secure communication channel.Firstly,the framework of high-capacity secure communication was constructed,and the features of channel data were analyzed,so as to provide the platform for the subsequent calculation.Secondly,the effective interference regions in communication were superposed,and the multi-target interference regions were integrated into a single interference area.Thirdly,the collaborative interference power allocation model was built by integer programming method,and thus to judge the interference degree for the attack goal and make corresponding anti-interference measures.Under the convergence of total power of high-capacity secure communication,the method of cooperative interference power allocation based on adaptive distribution was used to calculate the threshold value of channel switch based on the principle of speed maximization.Finally,the adaptive power allocation was realized by the principle of least mean square deviation.Thus,the error rate of channel transmission was reduced and the correctness of communication data was ensured.Simulation results show that the proposed method can reduce the interference power and ensure the high-precision transmission of channel data.In addition,this method greatly improves the anti-interference ability of communication channel,and it has good robustness.
