在本文中，我们研究了具有空间相关瑞利块衰落的两用户非相干多输入多输出广播信道。我们提出了一种利用统计信道状态信息（CSI）（即协方差矩阵的知识）的方案，并导出相应的可实现的自由度区域。该方案的主要思想是基于速率分割、加性叠加编码和信道训练。我们的结果表明，统计 CSI 在提高非相干广播频道的自由度方面可以发挥重要作用。
In this paper, we study the two-user non-coherent multiple-input multiple-output broadcast channel with spatially correlated Rayleigh block fading. We propose a scheme to exploit the statistical channel state information (CSI), namely, the knowledge of the covariance matrix, and derive the corresponding achievable degrees of freedom region. The main idea of the proposed scheme is based on rate-splitting, additive superposition coding, and channel training. Our result shows that statistical CSI can play an important role in enhancing the degrees of freedom of a non-coherent broadcast channel.
