移动网络通信中的遮挡衰减通信优化方法仿真

Simulation of Shielding Attenuation Optimization Method in Mobile Network Communication

移动网络通信过程中,在密闭空间中,物体遮挡会造成通信网络信号发生衰减。传统多径信道模型在处理信号衰减过程中,假定了遮挡环境中的重要系数掠射角不变。但是,实际操作中,掠射角随着环境不同会发生变化,从而造成多普勒频展干扰,通信受阻。针对上述问题,提出了一种改进径向基网络的遮挡通信优化方法。改进方法首先采用改进径向基网络预测多普勒频移产生时域干扰损耗,实现有效的快变信道预测,然后对抗多普勒频展及其引起的子载波间的干扰,提高移动网络通信过程中的遮挡通信的性能。仿真实验结果表明,改进方法在不同接收天线高度条件下的通信损耗,比传统方法更接近实际的通信损耗,有效优化遮挡通信的性能,降低网络通信损耗提高移动网络通信的效率。

This paper presented a blocking communication optimization method based on improved RBF network. In this method, the improved RBF network was used to predict interference loss in time domain of Doppler shift, so as to achieve effective fast-varying channel prediction, and then show its confrontation caused by the Doppler frequency interference between subcarriers to improve the performance of the communication block during mobile network com- munications. Simulation results show that the communication loss of this method in different reception antenna height, is closer to the actual communication loss than the traditional methods. The improved method can effectively optimize the performance of blocking communication and reduce network communication loss, and improve the efficiency of mobile network communication.
