本文提出了一种简单的两分支发射分集方案。该方案使用两个发射天线和一个接收天线，提供了与具有一个发射天线和两个接收天线的最大比接收机合并（MRRC）相同的分集阶数。它还表明，该计划可以很容易地推广到两个发射天线和M个接收天线，以提供2M的分集阶数。新方案不需要任何带宽扩展和从接收机到发射机的任何反馈，其计算复杂度与MRRC类似。
This paper presents a simple two-branch transmit diversity scheme. Using two transmit antennas and one receive antenna the scheme provides the same diversity order as maximal-ratio receiver combining (MRRC) with one transmit antenna, and two receive antennas. It is also shown that the scheme may easily be generalized to two transmit antennas and M receive antennas to provide a diversity order of 2M. The new scheme does not require any bandwidth expansion any feedback from the receiver to the transmitter and its computation complexity is similar to MRRC.
