摘要
多输入多输出(Multiple Input and Multiple Output,MIMO)信道的空间相关性极大程度上影响着MIMO系统的性能.基于相关统计建模的空间相关性MIMO信道模型,通过合理的软硬件划分,设计了一种高资源利用率的MIMO信道实时模拟方案,实现了实时MIMO信道模拟器.针对3GPP标准MIMO信道模型进行模拟,硬件模拟结果统计分析表明本方案模拟的MIMO信道特征能够与理论特征很好地吻合,具有良好的模拟精度.可扩展的信道模拟方案能够直接扩展到支持更多天线数目的 MIMO信道的实时模拟.
Spatial correlation of multiple input and multiple output（MIMO）channels has significant impact on the performance of MIMO systems.Based on the spatial correlation-based MIMO channel model,we presented a hardware resource-efficient real-time MIMO channel emulation scheme with reasonable hardware/software partitioning.Meanwhile,an emulator based on the presented scheme was implemented.The statistical analysis of the emulation results of 3GPP MIMO channel models agrees well with the theoretical reference.This scalable emulation scheme enables a straightforward implementation for much more complicated MIMO channel emulation with more antennas.
