摘要
设计一种面向复杂环境的通信信道自适应分配数学模型。根据网络拓扑结构,将通信信道基站划分为多个传输节点。考虑到复杂环境中信道间的干扰效应,通过量化干扰强度并设置环境参数监测周期,计算出每个信道的阻抗值。构建一个通信信道自适应分配数学模型,该模型以圆形作为干扰防护的基本覆盖区域,设定信道信噪比阈值以激活信道,为了评估模型性能,引入了信道利用效能指数(CUEI),该指数综合考量信道阻抗、发射功率及分配效率。实验结果表明,设计模型在50DB阻抗时仍保持在90MB,误码率在0.25%-0.7%范围内,具有实用性。
Design a mathematical model for adaptive allocation of communication channels in complex environments.According to the network topology,the communication channel base station is divided into multiple transmission nodes.Considering the interference effect between channels in complex environments,the impedance value of each channel is calculated by quantifying the interference strength and setting the environmental parameter monitoring period.Construct a mathematical model for adaptive allocation of communication channels,which uses circles as the basic coverage area for interference protection.Set a channel signal-to-noise ratio threshold to activate the channel.To evaluate the performance of the model,introduce the Channel Utilization Efficiency Index(CUEI),which comprehensively considers channel impedance,transmission power,and allocation efficiency.The experimental results show that the designed model still maintains 90MB at 50DB impedance and has a bit error rate in the range of 0.25%-0.7%,which is practical.
