文中在建立起Rayleigh衰减信道的基础上,构建了MIMO系统,在分析其系统性能后,提出并建立了在发射信噪比相同的情况下,分类重要信息与非重要信息,在接收端使重要信息具有更高信噪比G-MIMO系统模型及其系统性能分析;并在建立的G-MIMO系统模型下,将发送数据根据信道参数K的不同分时、分组发送,在不牺牲传输速率的前提下,提高了具有大信息熵消息的传输准确性。
Based on the established Rayleigh attenuation channel, a MIMO system is constructed. After analyzing its system performance, the paper proposes and establishes the classification of important information and non-important information under the same signal-to-noise ratio, The information has a higher signal-to-noise G-MIMO system model and its system performance analysis. In the established G-MIMO system model, the transmitted data is sent according to different timesharing of channel parameters K, without sacrificing the transmission rate Under the prerequisite, the transmission accuracy of message with large information entropy is improved.
