网格空时码（STTC）是一种空时编码技术。最先是由AT&T实验室的Tarokh等人在延时分集基础上结合TCM编码提出,STTC把编码和调制结合起来，综合考虑了编...

与同速率的满秩网格空时码相比，它能获得更好的误码性能，并且实现简单。
Compared with the full rank space-time trellis code (FR-STTC) with the same transmission rate, it can provide a better performance and a lower realization complexity.
然后对网格空时码（STTC）和分组空时码（STBC）的编译码原理、特点和性能进行了全面的分析；
Then the encoding and decoding theories, features and performances of STBC and STTC are detailed in all aspects.
但对分集增益而言，网格空时码和分组空时码均可达到系统所能提供的最大分集增益，而分层空时码由于受实现方式的制约，只能得到其中一部分分集增益。
But as to the diversity gains, STCM and STBC can achieve the maximum diversity that the system provides, while LST only obtains a small part of it because of its limited application.
