此函数用于产生脉冲超宽带系统的训练序列的波形。输出参数有三个：bits--发送的数据,stx--发送的信号,ref--参考信号 发送端调制方式为TH-PAM(The emerging ultra-wideband (UWB) system offers a great potential for high data rate wireless multimedia applications of the home entertainment and industry, as well as for low data rate sensor networks involving low power devices~cite{paragraph1}. One of the most acute challenges in realizing these potentials of the UWB systems is the timing acquisition. Timing errors as small as fractions of a nanosecond could seriously degrade the system performance~cite{paragraph21}. The difficulty in UWB synchronization arises from UWB signals being the ultrashort low-duty-cycle pulses operating at very low power density.)

Ardtool是Matlab的图形用户界面，用于分析天线阵列的不同类型。认识的天线辐射模式的程序，以及天线的类型分类编程(Ardtool is a Matlab graphical user interface for the analysis of the different types of antenna arrays. Understanding antenna radiation pattern procedures, and antenna type classification program)

本程序为《先进PID算法及其MATLAB实现》的matlab程序，验证好使(This program is the " advanced PID algorithm and MATLAB to achieve" the matlab program, verification so that)

边缘检测Canny法的源程序,网上好像有人需要，所以就放上来了(Canny edge detection method of the source, the Internet seems to be any need, therefore Fangshanglai!)

粒子滤波器,关于多目标跟踪的粒子滤波器，使用的是MATLAB仿真(JPDA)

说明：  层空时码有三种普遍的检测算法：最大似然（Maximum Likelihood ,ML）检测算法、迫零（zero forcing ,ZF）检测算法、最小均方误差（Minimum Mean Squared Error,MMSE）检测算法。(There are three layers in general space-time code detection algorithms: maximum likelihood (Maximum Likelihood, ML) detection algorithm, forcing zero (zero forcing, ZF) detection algorithm, minimum mean square error (Minimum Mean Squared Error, MMSE) detection algorithm.)
