论文摘要
本文开发了与多个用户相结合的速率分解技术(RS)多种用户的技术,以提高共同速率。我们提出了基于最小值,最大比率和最小均方误差标准的线性组合技术,以及基于RS的多源多重多ANTENNA系统的正则化块对角(RBD)预编码器。对总和率性能进行分析,导致封闭形式表达式。模拟表明,所提出的组合方案比常规线性预编码方案具有显着的总和率性能增长。
This paper develops stream combining techniques for rate-splitting (RS) multiple-antenna systems with multiple users to enhance the common rate. We propose linear combining techniques based on the Min-Max, the maximum ratio and the minimum mean-square error criteria along with Regularized Block Diagonalization (RBD) precoders for RS-based multiuser multiple-antenna systems. An analysis of the sum rate performance is carried out, leading to closed-form expressions. Simulations show that the proposed combining schemes offer a significant sum rate performance gain over conventional linear precoding schemes.
