随着纳米技术的不断发展与新型纳米材料石墨烯研究的不断深入，作为纳米网络通信技术的太赫兹通信成为无线通信的研究热点，然而现阶段对太赫兹通信中多输入多输出( MIMO)机制的研究较少。为此，采用离散化的数学方法，以接收端获取信道信息的遍历容量模型为基础，结合太赫兹信道的分子吸收噪声与传输路径损失，提出一种适用于太赫兹通信的MIMO信道模型。对建立的MIMO信道模型进行仿真与分析，结果表明，与单一太赫兹信道相比，太赫兹通信中的MIMO信道具有更高的信道容量与传输比特率。

With the development of nanotechnology and the graphene-based nano materials,terahertz communication, the preferred communication technology of nano network is becoming the new hotspot for wireless communication. However,the performance of Multiple Input Multiple Output( MIMO) channel in terahertz band is still unknown. A novel MIMO channel model in terahertz communications is proposed by using a discrete mathematical method. Combining the molecular absorption and the path loss in terahertz band,a model of channel capacity is presented based on the channel state information at the receiver. MIMO channel model in terahertz communications is verified in the simulation. Result shows that the MIMO channel in terahertz communication can support higher capacity and transmission bit-rates than the single terahertz channel.
