摘要
引入了准正交方阵嵌入码的概念,提出了一种新颖而简单的方阵嵌入空时分组码的设计方法。在生成同样性能码矩阵的情况下,本文提出的构造公式与已有设计方法相比要简单得多。文章还给出了准正交方阵嵌入码的特性,并结合仿真结果对其性能进行了分析。
We introduce the concept of quasi-orthogonal square-matrix embeddable codes (QOSMEC) and propose a new simple design method to construct the square-matrix embeddable space-time block codes. As compared to the previous works, the construction formulas presented here are much simple with the same performance of the code matrices constructed. Furthermore, the properties of the QOSMEC are presented and the performance is analyzed based on the simulation results.
