本文考虑了在发射机和接收机处具有信道知识的多输入多输出（MIMO）通信系统的设计。文献中可用的设计方法已经解决了问题的以下两个方面：a）针对给定传输方案选择符号星座，或者B）针对星座的给定选择选择最优（线性）预编码器和均衡器。更具体地说，星座的选择是强制对角或平行传输。然而，在实践中，选择星座和线性预编码器/均衡器这两个问题是明确耦合的，并且对角结构可能不一定是最好的。本文试图通过弥合关于星座的选择和关于线性收发器形式的信号处理的设计的现有结果之间的差距来提供该问题的全局视图（即，发射机处的预编码和接收机处的均衡）。
This papers considers the design of a mutiple-input multiple-output (MIMO) communication system with channel knowledge at the transmitter and receiver. The design methods available in the literature have addressed the following two aspects of the problem: a) choice of the symbol constellations for a given transmission scheme or b) choice of the optimal (linear) precoder and equalizer for a given choice of the constellations. More specifically, the choice of the constellations has been made enforcing a diagonal, or parallel, transmission. However, in practice, the two problems of choosing the constellations and the linear precoder/equalizer are clearly coupled, and the diagonal structure may not be necessarily the best. This paper attempts to provide a global view of the problem by bridging the gap between the existing results on the selection of the constellations and on the design of the signal processing in the form of a linear transceiver (i.e., precoding at the transmitter and equalization at the receiver).
