摘　　要：阐述VHF频段无线通信的特点,提出一种在强干扰环境下实现VHF通信的技术,该技术利用天线间距大于1倍波长时各天线相关性较弱的特点,借鉴MIMO的空间复用思路,对强干扰环境下的VHF信号进行了有效分离,提高接收机的信干噪比SINR。This paper describes the characteristics of VHF frequency band wireless communication and proposes a technology to achieve VHF communication in strong interference environments.This technology utilizes the weak correlation between antennas when the antenna spacing is greater than one wavelength,and draws on the spatial multiplexing concept of MIMO to effectively separate VHF signals in strong interference environments,improving the signal-to-noise ratio(SINR)of the receiver.

关 键 词：超短波 多输入多输出 信干噪比 抗强干扰通信
