研究了多输入多输出（MIMO）在体域网络（BAN）中的应用。研究了在室内环境下进行随机运动时，MIMO子信道与MIMO信道容量之间的相关性。一些MIMO子信道被发现是相关的。然而，由于使用MIMO，仍然观察到显着的容量增加，从而证明了在BAN通信中使用MIMO的可行性。本文还提出了一种简单的利用中断传输的BAN-to-BAN抗干扰方法，其抗干扰增益明显高于两种传统的抗干扰方法。
The application of multiple-input multiple-output (MIMO) in body-area networks (BAN) is considered in the paper. The correlations between MIMO sub-channels and the MIMO channel capacity are investigated for three on-body channels when random movements are performed in an indoor environment. Some of the MIMO sub-channels were found to be correlated. Nevertheless, a significant capacity increase due to use of MIMO was still observed thus demonstrating the feasibility of using MIMO in BAN communications. A simple BAN-to-BAN interference rejection method which makes use of interrupted transmission is also proposed in the paper, and is shown to produce interference rejection gains significantly higher than those produced by two conventional interference rejection methods.
