| 摘 要： | 针对多输入多输出（Multiple-Input Multiple-Output,MIMO）无线通信系统，在基于Kronecker 的MIMO信道模型中综合考虑了路径损耗、阴影衰落和多径衰落等因素，实现了基于现场可编程门阵列（Field Programmable Gate Array，FPGA）的MIMO信道模拟器，并分析了硬件设计方案以及MIMO信道模拟的实现方法。实测结果表明，设计的MIMO信道模拟器可以模拟瑞利衰落、莱斯衰落以及阴影衰落等常见的信道衰落类型，能够应用于3GPP、COST-207等标准信道模型的复现。该模拟器可作为无线通信系统研究的测试设备，辅助通信系统研究的算法验证、方案优化以及性能分析。

| Abstract: | For Multiple-Input Multiple-Output(MIMO) wireless communication systems,this paper adopts a Kronecker-based MIMO channel model which includes path loss,shadow fading and multipath fading.Based on the proposed model,a new MIMO channel emulator is designed and implemented on a field programmable gate array(FPGA) hardware platform.Meanwhile,the hardware realization scheme as well as the channel fading emulation method are analyzed.Measured results show that the proposed MIMO channel emulator can reproduce many fading types,i.e.,Rayleigh fading,Rice fading and shadow fading,as well as some standard channel models,i.e.,3GPP model and COST-207 model.It can be used as a test equipment of wireless communication systems for algorithm validation,scheme optimization and performance analysis. |
