基础设施无线网状网络因其在公共无线接入、传感器网络等领域的广泛应用而备受关注。近年来，研究人员已经表明，通过在无线环境中使用网络编码可以实现显着的网络吞吐量增益。为了进一步提高一维（1D）拓扑下的网络吞吐量，Ono等人提出使用多天线技术结合网络编码。本文受一维拓扑结构中MIMO网络编码的启发，建立了一种新的二维拓扑结构中由两条交叉路由组成的MIMO网络编码算法。该算法将多个网络编码流进行空间复用。由于有效利用了网络编码的无线资源和MIMO的同信道干扰消除能力，在最佳情况下，该算法的网络容量比传统方法增加了8倍。
Infrastructure wireless mesh network has been attracting much attention due to the wide range of its application such as public wireless access, sensor network, etc. In recent years, researchers have shown that significant network throughput gain can be achieved by employing network coding in a wireless environment. For further improvement of network throughput in one dimensional (1D) topology, Ono et al. proposed to use multiple antenna technique combined with network coding. In this paper, being inspired by MIMO network coding in 1D topology, the authors establish a novel MIMO network coding algorithm for a 2D topology consisting of two crossing routes. In this algorithm, multiple network coded flows are spatially multiplexed. Owing to the efficient usage of radio resource of network coding and co-channel interference cancellation ability of MIMO, the proposed algorithm shows an 8-fold gain in network capacity compared to conventional methods in the best-case scenario.
