应用软件无线电（SDR）实现MIMO通信实验研究

移动通信系统通过四代的发展变革,在5G的大规模商用下,多输入多输出(MIMO)技术凭借本身的特殊优点已经成为了5G的核心技术,MIMO具备着可在不用增加功耗的条件下提升无线系统性能的优点。它在应用多个天线时,传输的信号以信道分集的方式得到容量增益,凭借不同无线信道传输至接收天线。主要工作及创新点如下:(1)基于USRP平台设计了MIMO系统。(2)提出了解决设备相位同步的方案。

Expermental Research on MIMO Communication Using Software Defined Radio(SDR)

In the context of large-scale commercial use of 5 G,mobile communication systems have undergone four generations of transformation.Multiple Input Multiple Output(MIMO)technology has become the core technology of 5 G with its own special advantages.Using MIMO can improve the performance of wireless systems without increasing power consumption.When it uses multiple antennas,the transmitted signal gets the capacity gain through channel diversity,and is transmitted to the receiving antenna with different wireless channels.The main work and innovations of this thesis are as follows:(1)Designed a MIMO system based on the USRP platform.(2)Proposed a solution to the phase synchronization of equipment.
