VBLAST可以有效提高多发射天线系统容量，而STBC则具有较高的分集增益，通过将两种方案结合起来组成一个新的系统。
The VBLAST can be used to exploit the capacity potential provided by multiple transmit antenna systems. The STBC has higher diversity gain.
为了使数据可靠地传输，链路设计中往往盲目加大发射机功率，提高天线增益来提高系统的余量。
For the purpose of reliable transmission, the system margin is increased blindly through enhancing the transmitter power or the antenna gain in link design.
用有限的空时码进行扩谱，并利用较少的发射天线和接收天线进行信号的发射与接收，从而在TD _ SCDMA移动接收端获得最大的扩谱增益。
Base_station USES finite number of space_time codes to spread, and small number of antennas to transmit and receive signal, thus TD_SCDMA mobile terminals can obtain maximal spreading gain.
