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)

八单元线阵的DOA估计的MUSIC算法实现。可以看出music方法分辨率较高。这里用的是36度方向下的weight,自己也可以尝试其他的天线weight值。 (eight modules Array DOA MUSIC algorithm. Music can be seen higher resolution method. Here is the direction of 36 degrees under the weight, they could also try to the other antenna weight values.)

Fiber Bragg Grating reflectivity.

说明：  使用ziegler方法，对PID控制器进行PID整定。(Using Ziegler method, the PID controller is tuned.)

MUSIC(Multiple Signal Classification)算法是Schmidt在1979年首先提出的，是早期经典的超分辨率DOA估计方法(即超瑞利限的方法)，属特征结构的子空间方法。(MUSIC (Multiple Signal Classification) algorithm is Schmidt first proposed in 1979, is an early classic super-resolution DOA estimation methods (ie, super-Rayleigh limit of the method), is a characteristic structure of the sub-space method.)

扩散系统之浓度分布的装置。管中储放静止液体B，高度为L=10 ㎝，放置于充满A 气体的 环境中。假设与B 液体接触面之浓度为3 C 0 0.01mol m A = ，且此浓度不随时间改变 而改变，即在操作时间内( h = 10天)维持定值。气体A 在液体B 中之扩散系数为 D m s AB = 2×10− 9 2 。试决定以下两种情况下，气体A溶于液体B中之流通量(flux)。 (a) A 与B 不发生反应； (b) A 与B 发生以下之反应 A+ B→C ， A A − r = kC 其反应速率常数k = 2×10− 7 s− 1。 (Diffusion system of concentration reference device shown in Figure 3. Tube in the store still liquid B, L = 10 cm height, placed in full A gas environment. Assuming the contact surface of the liquid with the B concentration of 3 C 0 0.01mol m A =, and this concentration does not change with time and change, that is, the operating time (h = 10 days) to maintain constant. Gas A in liquid B, the diffusion coefficient D ms AB = 2 × 10-9 2. Decided the following two test cases, the gas dissolved in liquid B in the A liquid (flux). (A) A and B do not react (b) A and B of the following reaction occurs A+ B → C, AA- r = kC, the reaction rate constant k = 2 × 10-7 s-1.)
