摘要
采用自主搭建的信道测量平台测得了机舱环境下分布式MIMO系统的信道冲击响应矩阵。根据实测的信道矩阵分别计算了4种具有不同收发天线数目的分布式MIMO系统的信道容量。为了便于比较,SISO系统的信道容量也通过实测数据进行了计算。计算结果表明:在机舱环境下,采用分布式MIMO系统和采用SISO系统相比能够显著提高系统信道容量,说明分布式MIMO系统可以充分满足未来机舱内无线通信高速率数据传输的需求。
With the self-built channel measurement platform,the channel matrix of in-cabin distributed MIMO system is measured.The channel capacity of 4 different distributed MIMO systems and also the channel capacity of one SISO system are calculated from the measured data.The calculation results show that as compared with one SISO system,the distributed MIMO system could significantly raise the capacity gain in the aircraft cabin environment,and thus could fully satisfy the requirements of high data-rate delivery for future in-cabin wireless communication.
