摘要

现代电信系统迫切需要高数据速率以提高接收质量。高数据速率可以通过增加带宽来实现。由于带宽是一种有限的资源，我们研究了一种通过分集增益提高通信系统的数据速率来最大化系统性能的方法。这源于空时分组编码(STBC)提供的多输入多输出(MIMO)方案。该方法利用Hadamard矩阵形成拟正交STBC (QO-STBC)码结构，使检测矩阵中不存在非对角项，从而使系统性能最大化。根据分析规定，该编码结构显著提高了MIMO系统的性能。

A simple space-time coding technique for wireless communication systems

Modern telecommunication systems are piqued for/by high data rate to improve reception quality. High data rate can be, naively, achieved using increased bandwidth. Since bandwidth is a limited resource, we study a method of maximizing system performance by improving data rate of communication systems via diversity gain. This followed from multiple input multiple output (MIMO) scheme provided by space-time block coding (STBC). The new method uses Hadamard matrices to form a quasi-orthogonal STBC (QO-STBC) code structure that is void of some off-diagonal terms in the detection matrix thus maximizing the system performance. The code structure significantly improves the MIMO system performance consequent on the analytical provisions.
