The-Application-and-Study-of-Antenna
以天线方向图函数为例，分析了对称阵子天线、阵列天线方向图函数F(0， )随各参量变化的规律以及二维图形的特点，并讨论了直线天线阵(单向端射阵)的最大辐射方向和主瓣宽度随各参量变化的二维、三维图形特点。借助MATLAB的绘图功能，对各种天线的方向图函数的二维、三维图形进行研究，可以观察到天线辐射场在不同方向的辐射能量分布。直观清楚地表现出辐射方向图的特点。(Antenna pattern functions as an example to analyze the symmetry time around antenna array antenna pattern function F (0,) with each variation of parameters and characteristics of two-dimensional graphics, and discussed the linear antenna array (one-way end-fire array) The maximum radiation direction and the width of the main lobe of each parameter change with 2D and 3D graphics features. With MATLAB graphics functions for 2D and 3D graphics in a variety of antenna pattern function were studied, the antenna radiation field can be observed in the distribution of radiation energy in different directions. Features an intuitive clear demonstration of the radiation pattern.)

频率估计
1）产生一个单频实信号，加上一定信噪比的噪声。
2）对含噪声的信号进行频率估计。估计方法可以查阅相关文献。
3）统计估计出来的频率和真实频率之间的误差。
4）验证该频率估计算法在不同信噪比、不同数据长度下、不同频率时候的性能。
(Frequency estimation 1) produce a single-frequency real signal, plus a certain SNR noise. 2) noisy signal frequency estimates. Estimation method can access relevant literature. 3) out of the statistical estimation and frequency error between the true frequency. 4) Verify that the frequency estimation algorithm under different SNR, different data length, when the frequency of different properties.)

OFDMSYN
说明： OFDM系统是将一个用户的信息分别调制在了多个相互正交的子载波上面，对频率偏移非常敏感，OFDM同步技术非常关键，这里予以实现(OFDM system is a user' s information were prepared in a number of mutually orthogonal subcarriers above, is very sensitive to frequency offset, OFDM synchronization is critical to achieve here)
