    摘要:

    针对三维(3D)大规模多输入多输出(MIMO)系统中莱斯信道模型,通过研究分析获得简单易行、频谱效率高的传输方案。考虑到莱斯信道中的散射信道获取较为困难,而视距信道获取较为容易,仅利用视距信道进行传输方案研究。首先通过用户调度算法解决了相邻用户之间干扰过大的问题,从而提升了系统的和速率;接着充分利用3D MIMO系统中水平和垂直维度的特点,采用域选择的预编码方法消除不同用户间的干扰并最大化信噪比,进一步提升了系统和速率。经过仿真验证,提出的3D大规模MIMO传输方案比以往方案具备更大的频谱效率。

    Abstract:

    The 3D massive Multiple Input Multiple Output(MIMO) under the Rician channel model is studied, and the easily-implemented transmission scheme with high-spectral efficiency is proposed. The proposed scheme only utilizes the Line-Of-Sight(LOS) channel, as it is easier to be obtained than the scatter channel. Firstly, the user scheduling algorithm is utilized to solve the problem of too much interference between adjacent users, so as to improve the sum rate of the system, and then the precoding method of domain selection is utilized to eliminate the interference between different users and maximize the Signal-to-Noise Ratio(SNR), so as to further improve the system sum rate. The simulation results validate that the proposed scheme has higher spectral efficiency than the previous schemes.
