This system can work in two modes: fixed star detection mode and moving space target tracking mode.

系统可工作于两种模式：恒星目标检测定位模式和运动空间目标检测跟踪模式。

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。
