摘要:

针对正交空时分组码(O-STBC)达不到满速率的情况,基于Tarokh的空时编码设计准则,提出了一种新的满速率准正交空时编码(Q-O-STBC)矩阵,再经过适当的调制星座旋转得到满分集Alamouti空时星座旋转(A-STCR)分组码.介绍了A-STCR编码的编码结构与译码方法,证明了该编码的有效性.对A-STCR编码的性能进行了Matlab仿真,并与其他空时分组码作了比较,证实了A-STCR分组码的性能优越型.

关键词: 空时分组码, 满速率, 满分集, 星座旋转

Abstract:

Focusing on the case that existing orthogonal space-time block codes (O-STBC) have not achieve full rate, a type of novel transmit matrix for quasi-orthogonal space-time block code (Q-O-STBC) is proposed based on Tarokh`s design criterion of space-time code. A full diversity space-time constellation-rotating (A-STCR) block code is obtained through appropriate modulation constellation rotating. It is introduced the encoding structure and decoding principle of A-STCR code. The validity of this coding is proved. The performance merit of A-STCR block codes is confirmed by Matlab simulations and compared with other space-time block codes.

Key words: space-time block codes, full rate, full diversity, constellation-rotating
