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.)

说明：  谢菲尔德大学的MATLAB遗传算法工具箱，已经试过，很好用，在这里分享给大家。完全解压后将文件放到matlab的toolboxs里，再打开matlab的set path添加保存(The MATLAB Genetic Algorithm Toolbox at the University of Sheffield has been tried and used very well and is shared here. After fully decompressing, put the file into the toolbox of matlab, and then open the set path of matlab to save it.)

基于海图的快速临近值插值进行地图构建，并根据水下机器人的动力学模型，利用遗传算法进行全局路径规划。(The map is constructed based on the fast approaching value interpolation of the sea chart, and the global path planning is carried out by the genetic algorithm according to the dynamic model of the underwater robot.)

This toolbox is used to develop software defined radio for GPS receiver

说明：  数字信号的调制识别，提取了信号的时域特征与频域特征。包含神经网络训练。(Modulation recognition of digital signal.The time-domain and frequency-domain features of the signal are extracted. Including neural network training.)
