摘要

视距MIMO (LOS-MIMO)具有极大提高回程网络中微波链路容量和频谱效率的潜力。在本文中，我们介绍了在单通道和非同步振荡器中具有四个空间流的单极化LOS-MIMO系统的室外实验结果，我们在14 MHz通道中获得了40.2 bps/Hz的非编码频谱效率，误码率为6.6\cdot 10^{-3}$。我们还讨论了系统的性能限制。

A 40.2 bps/Hz Single Polarization 4x4 Line-of-Sight MIMO Link With Unsynchronized Oscillators

Line-of-sight MIMO (LOS-MIMO) has the potential to greatly improve the capacity and spectral efficiency of microwave links in backhaul networks. In this paper we present results from an outdoor experiment with a single polarization LOS-MIMO system with four spatial streams in a single channel and unsynchronized oscillators, with which we achieve an uncoded spectral efficiency of 40.2 bps/Hz for a 14 MHz channel with $6.6\cdot 10^{-3}$ bit error ratio. We also discuss the performance limitations of the system.
