摘　　要：该文提出了一种基于软件无线电技术可动态配置的动态信道模拟方法,根据静态、动态与生灭信道的复杂度动态配置FPGA。信道参数经过计算后传递给信道参数存储单元,根据信道刷新速率实时配置给FPGA信道模拟单元得到的多通道IQ基带信号,再将IQ基带信号正交变频到载波上。最后给出了多组实验数据,实验结果证明了动态配置的动态信道模拟方法的可行性和实用性。A dynamic channel simulation method based on software radio technology is proposed in this paper, which can dynamically configure FPGA according to the complexity of static,dynamic and birth-death channels. After calculation,the channel parameters are transmitted to the channel parameter storage unit.The multi-channel IQ baseband signal is obtained by the FPGA channel simulation unit which is allocated by the real-time channel parameters according to the channel refresh rate.And then the IQ baseband signal is orthogonally converted to the carrier.Finally, several groups of experimental data are given,and the experimental results prove the feasibility and practicability of the dynamic channel simulation method with dynamic configuration.
