摘　　要：已有的通信信道容量控制方法忽略了构建无线通信信道模型,无法整体分析通信安全问题,导致传统方法存在无线通信信道利用率低、信道容量小和信道抗干扰能力差的问题。为此提出智能化无线通信信道安全容量控制方法。建立无线信道模型,计算通信天线发射端的天线阵列方位角,获取容量平均近似空间函数,整体有效分析无线通信信道。将cluster态作为量子信道,实现安全检测和信道安全容量控制。实验结果表明,智能化无线通信信道安全容量控制方法的信道利用率高,加入20dB噪声后信道容量控制效果仍然较优,实验结果验证了上述方法的实用性高,可广泛应用。At present, traditional methods ignore the construction of wireless communication channel model and cannot analyze the communication security problem in general, which leads to the problems of low utilization of wireless communication channel, small channel capacity and low anti-interference ability. Therefore, an intelligent method to control the safe capacity of wireless communication channel was proposed. Firstly, the wireless channel model was built and the azimuth angle of the antenna array at the transmitting end of communication antenna was calculated. Then the average approximate spatial function of capacity was obtained. Moreover, the wireless communication channel was effectively analyzed. On this basis, the cluster state was taken as a quantum channel. Finally, the security detection and the control for safe capacity of channel were achieved. Experimental results show that the channel utilization rate of the proposed method is high;Meanwhile, the control effect for channel capacity is still better after adding 20 dB noise. In addition, this method has high practicability, which can be widely applied.
