In this paper, a novel general design method of quasi-orthogonal space-time block codes for four antennae is presented.

本文提出了一种新的四天线准正交空时分组码的通用设计方法。

Whereas the non-orthogonal space-time block codes which obtain higher transmission rate at the cost of orthogonality and partial diversity gain may degrade the performance.

而以牺牲正交性和部分分集增益为代价来获得更高传输速率的非正交空时分组码又会使误码性能降低。

Focusing on the problem that existing linear dispersion (LD) space-time codes have a high encoding and decoding complexity, a type of orthogonal linear dispersion (OLD) space-time codes is proposed.

针对多输入多输出系统中现有的线性分散(LD)空时码编、解码复杂度高的问题，提出了一类正交线性分散(old)空时编码。

Orthogonal linear dispersive space time code can also be used as an adaptive one for different application requirement.

根据不同的传输需求，正交线性空时弥散码的形式还可以灵活变化。

In this paper, the orthogonal projection approximation subspace tracking (OPAST) is employed for channel estimation and space-time multiuser detection in space-time block coded MIMO system.

文章提出在空时分组编码的MIMO系统中利用OPAST这种子空间追踪算法进行盲空时多用户检测。

Orthogonal transmit diversity (OTD) and space-time spreading (STS) have been included in the 3gpp2 standard, while space-time transmit diversity (STTD) is one part of the 3gpp standard.

包括应用在3gpp 2标准中正交传输分集(otd)和空时扩频(STS)，另外空时传书分集作为3gpp传输标准的一部分。
