摘要
无线信道多径传输特性是影响无线通信系统性能的重要因素之一。给出了利用抛物方程模型获得无线传输信道的冲击响应函数的方法,该方法具有计算简单、精度较高的优点。利用2D抛物方程模型对不同场景下的多径信道脉冲响应函数进行了预测仿真,仿真结果表明了基于抛物方程模型的多径信道脉冲响应函数预测模型的可行性和精确性。
The multipath propagation is one of the most important factors which can impact the performance of wireless communication system. The method is proposed to get the impulse response function of propagation channel just from the results of parabolic equation models. The method has such advantages as simple computation and high accuracy. The predictive simulation is performed for multipath channel impulse response function in different scenarios by using 2D parabolic equation model. The simulation results prove the feasibility and accuracy of multipath channel impulse response function predictive model based on parabolic equation model.
