In this paper, we present a novel data-based method for simultaneous Maximum Likelihood
(ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision
multiplexing (OFDM) systems. Statistical properties introduced by the cyclic
pre痻, a guard space between OFDM symbols, provide su眂ient information about the
unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻
allows the estimation to be performed without additional pilots. Simulations show that
the performance of the frequency estimator is applicable in a tracking mode while the
timing estimation can be used in an acquisition mode.

Quickplot
本人自编的一个快速作图,功能强大的matlab GUI 界面程序。其主要功能如下:
1.导入工作空间变量(X,Y):导入工作空间变量,并提取类型为数组的变量。
2.绘图(plot):多种模式,包括1对1,1对多,多对多。如x1—y1 x1—y1,y2;x1,x2—y1,y2。
3.快速标准化图形(NormalFig):快速设置图形格式,以达到论文图片要求。字体大小,线型粗细等
4.可以手动设置格式
5.可以设置为笛卡尔坐标,也可以设置为对数坐标
6.右键执行命令:“Execute”旁的可编辑框,输入命令,右键执行。右键执行的好处是:可以保存变量到工作空间,实现非连续执行命令。
7.符号函数简易绘图(Ezplot):快速绘制函数图,并可设置区间,区间设置用“ ”隔开。
8.锁定(lock):锁定,即图形绘制在GUI坐标轴内;解锁,新建Fig,绘制图形,方便输出
9.保持和编辑(Hold,EditPlot),编译后exe,亦可对图形进行拾取设置
另还有对变量转置等功能。
整个程序中,如操作失误,每处错误都有提示。
(It is a matlab program,which can help you plot beautiful figures easily,or make you learn some programming skills. In a word,it is a useful program and tool.)
