exm1001_1

This project is under Digital image processing. The project helps us to identify the smoke present in the images, the source code is written by matlab scripting.

用MATLAB实现fft变换，很easy，源代码如下(MATLAB，fft)

生成巴克码并画出其频域图，还可以生成复合信号(bark code and its spectrum)

qpsk modulation ofdm main papr

带可调渐消因子的无迹卡尔曼滤波程序MATLAB仿真实例(With adjustable fading factor unscented Kalman filtering procedures MATLAB simulation examples)

基于FrFT的时变幅度LFM信号参数估计，采用二维峰值搜索算法，后用一维曲线拟合，大大减少了计算量。(The parameter estimation of LFM signal based on FrFT is based on two dimensional peak search algorithm and one dimension curve fitting, which greatly reduces the computation.)

利用optisystem软件仿真半导体激光器的P-I特性曲线。得到的图形遵循在超过阈值电流之后，输出光功率与电流成线性关系规律。(Using software optisystem simulation P- I characteristics of semiconductor laser curve.The graphics follow after more than threshold current, a linear relationship with the output light power and current laws.)

BPSK调制在AWGN信道下的通信系统的matlab仿真程序(BPSK modulation in AWGN channel of communication system simulation program matlab)

matlab程序，四种不同的信号，在4个区域显示(matlab program, four different signals, in the four regions showed)
