在过去的几年中，已经提出了许多用于多发射天线系统的空时分组码。提出了一种利用群相干码（GCCs）将m个发射天线的空时码扩展到m个p个发射天线的方法。gcc利用来自接收器的非常有限的反馈（低至1位）。特别是，该方案可用于将任何正交码（如Alamouti码）扩展到两个以上的天线，同时保持低解码复杂度，充分的分集优势和充分的数据速率。
During the last few years a number of space-time block codes have been proposed for use in multiple transmit antennas systems. We propose a method to extend any space-time code constructed for m transmit antennas to m p transmit antennas through group-coherent codes (GCCs). GCCs make use of very limited feedback from the receiver (as low as 1 bit). In particular the scheme can be used to extend any orthogonal code (e.g., Alamouti code) to more than two antennas while preserving low decoding complexity, full diversity benefits, and full data rate.
