摘　　要：针对MIMO无线信道仿真器中相关衰落模拟需求,提出一种基于mesh网络的高速数据交互方法。通过多通道天线拆分的同步基带数据流与相关信道矩阵数据实时运算处理后,再进行多通道天线数据合并得到所需基带信号。对多普勒频移、多径测试、MIMO相关性衰落特性等时频域测试与分析验证,结果表明该设计能够实现宽带8×8 MIMO信道相关性运算和信道仿真。为大规模MIMO无线信道模拟器的系统集成研制提供技术基础,具有一定的实用价值。A high-speed data exchange method based on mesh network is processed for the correlation fading simulation requirements in MIMO wireless channel simulator.After the real-time matrix operation of the related matrix data and the stream of synchronous baseband data which is processed by the multi-channel antenna splitting,the required baseband signal is obtained by the data merging of the multi-channel antenna.Through the test and analysis in time and frequency domains,the results show that this design can realize the correlation calculation and channel simulation of 8×8 broadband MIMO.It provides a technical basis for the development of large-scale MIMO wireless channel emulator system integration and offers practical applicable value.
