在信号发送后，接收方需要实现位同步才能正确解码(after signal is sent, receiver need bit syn to decode correctly)

这是一个用VC编写的MSCOMM控件的注册安装示例工程源代码，对于单片机的上位机软件开发是一个不错的小工具(This is a prepared using VC control register MSCOMM sample project to install the source code for the MCU PC software development is a good gadget)

基于DGTD方法的高效天线建模与仿真研究(Leap-frog discontinuous Galerkin timedomain method)

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.)
