DFTOFDM

transducer design for ceramics pzt-4

利用该源码程序可在归一化频率轴上绘出归一化的功率谱曲线。(Use of the source program can be in the normalized frequency axis mapping normalized power spectral curve.)

微分先行PID算法，MATLAB语言编写，仿真效果不错。(Differential first PID algorithm, MATLAB language, simulation results are good.)

Discrete Fourier Transform in MATLAB

说明：  对信道的仿真，采用QPSK调制，分别在瑞利和高斯信道条件下，也包括CRC较验(Simulation of the channel, using QPSK modulation, respectively, Rayleigh and AWGN channel conditions, but also more experience CRC)

用matlab实现画彩色花朵的动画，对初学matlab的同学能有帮助。(Using matlab to achieve colored flowers painted animation, matlab for beginner students can help.)

DC load flow is a method to estimate power flows through lines on AC power systems. It uses a modified version of AC load flow using a linearized version of it. Programming is done in Matlab.

说明：  为大型相控阵天线真面进行调整优化，是阵面方向图达到要求(For large phased array antenna to adjust and optimize the real face is the front up to the required patterns 搜索)

基于matlab的一维条形码识别程序，条码为通用的EAN一13条码 (The bar code recognition program based on MATLAB)

说明：  加信噪声，单边带调幅，设计波特滤波器，过滤噪声，比较经过希尔伯特变换前后的区别(Plus letter noise, single-sideband amplitude modulation design Potter filters, filter noise comparison, after the difference between before and after the Hilbert transform)
