摘要

块对角化(BD)是一种多用户多输入多输出(MIMO)广播信道的线性预编码技术，可向同一小区的不同用户发送多个无干扰的数据流。本文研究了存在空间相关性的多用户多输入多输出(MIMO)系统的块对角化容量。提出并验证了带功率分配方案的优化对角化技术。

Performance of block diagonalization scheme for multiuser MIMO downlink heterogeneous channels

Block diagonalization (BD) is a linear precoding technique for multiuser multi-input multi-output (MIMO) broadcast channel that sends multiple interference free data streams to different users in the same cell. In this paper, we investigated the capacity of a multiuser multiple input multiple output (MIMO) system employing the block diagonalization scheme in presence of spatial correlation. The optimized diagonalization technique with power allocation scheme is proposed and verified.
