    摘要:

    随着灯光与光无线通信技术的结合，基于LED的可见光通信（VLC）越来越受到人们的关注.本文首先探讨了可见光通信的基带处理过程.为了提高室内照明度，LED阵列渐渐被广泛使用，基于此，可见光通信系统中基于LED阵列的MIMO技术也进入研究者的视野，因此，随后介绍了两种VLC-MIMO机制，并介绍了空时分组编码（STBC）在VLC-MIMO系统中的研究进展.作为对比，最后对LTE系统中的物理层处理过程和多天线技术进行技术探讨，并大胆预测了可见光通信基带处理后续可能发展的方向.

    Abstract:

    Visible Light Communication (VLC) attracts more and more interest since the combination of optical wireless communication with LED.LED array also becomes much popular in order to improve indoor lighting,so the VLC-MIMO based on LED array has arisen.The baseband processing of the VLC system is introduced in this paper,followed by two VLC-MIMO systems and the research progresses of Space-Time Block Code in VLC-MIMO.The physical channel processing and multiple antenna technology in long term evolution are discussed,and the future development of VLC system is predicted.
