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: This thesis presents simulation data on array operation in wideband communication systems.
It is shown that array structures with closer inter-element spacing outperform structures with
much larger inter-element spacing. It is also shown that circular structures outperform linear
structures. This performance di erence between the classi cations of arrays is due largely
to the circular array s ability to handle high levels of interference. Even though a diversity
combining scheme (MRC) was used in the simulator, the arrays provided interference rejection
capabilities due to the closely spaced antenna elements. Platform: |
