Description: MIMO指多输入多输出，MIMO技术大致可以分为两类：发射/接收分集和空间复用。传统的多天线被用来增加分集度从而克服信道衰落，具有相同信息的信号通过不同的路径被发送出去，在接收机端可以获得数据符号多个独立衰落的复制品，从而获得更高的接收可靠性。这种技术往往要结合多天线技术，而多天线技术在移动通信中得到了广泛的研究。-MIMO refers to Multiple Input Multiple Output, MIMO technology can be broadly classified into two categories: transmit/receive diversity and spatial multiplexing. Traditional multi-antenna was used to increase the degree of diversity to overcome channel fading, the signal with the same information through different paths have been sent in the receiver-side data symbols can be multiple independent copies of the decline, which was higher reception reliability. This technology often have to combine multi-antenna technology, and multi-antenna technology in mobile communication has been widely studied. Platform: |

Description: An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this
paper. With simple linear operations at both transmitter and receiver, the proposed algorithm can achieve better
system performances with only 2M − 2 bits of feedback information for systems with M transmit antennas.
Theoretical performance bounds of the proposed transmit diversity scheme are derived. Simulation examples and
theoretical analyses show that the proposed transmit diversity scheme outperforms not only the conventional openloop
transmit diversity techniques, but also some closed-loop transmit diversity techniques with more information
transmitted in the feedback channel.-An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this
