| 摘 要： | 在多用户MIMO(多输入多输出)中继通信系统中研究了基站预编码和中继处理矩阵的优化设计问题,提出了一种能有效消除多用户干扰的基站预编码方案——迫零QR,并采用奇异值分解(SVD)法设计了中继处理矩阵.仿真结果表明,所提的迫零QR预编码方案的和速率随着天线数的增加和用户数的增加而增大,且明显优于基站无预编码策略,若与SV...

| Abstract: | The optimized design of base station precoder and relay processing matrix is investigated in multi-user MIMO(Multiple-Input Multiple-Output) relay communication systems.A base station precoder scheme,called zero-forcing QR,is proposed to eliminate the multi-user interference efficiently,and the relay processing matrix based on singular value decomposition(SVD) is also designed.The simulation results show that the sum rate of the proposed zero-forcing QR procoding scheme increase with the number of the antennas and the number of the users,and outperform the scheme without the precoder,and the zero-forcing QR combined with SVD relaying scheme can further improve dramatically the system sum rate performance. |
