基于MIMO算法或网络编码的高效双向多跳无线网络已在最近的论文中被提出。本文提出了一种新的多跳中继网络编码技术--MIMO网络编码技术，即网络编码与MIMO算法相结合的技术。通过使用MIMO网络编码，可以在多跳网络中以较低的复杂度同时实现同信道干扰消除和高效的双向传输。此外，空时分组码（STBC）MIMO传输也被引入，以实现更高的可靠性在MIMO网络编码。数值分析表明，采用空时分组码的MIMO网络编码比传统方案具有更高的容量和可靠性。
Efficient bi-directional multi-hop wireless networks based on MIMO algorithm or network coding have been proposed in recent papers. This paper proposes a new technique named as MIMO network coding, that is a combination of network coding and MIMO algorithm for multi-hop relay networks. By using MIMO network coding, co-channel interference cancellation and efficient bi-directional transmission can be realized simultaneously with lower complexity in multi-hop networks. Moreover, Space Time Block Code (STBC) MIMO transmission is also introduced to achieve higher reliability in MIMO network coding. It is confirmed from numerical analysis that the MIMO network coding with STBC achieves higher capacity and reliability than conventional schemes.
