2010年吉林省数学建模大赛A题matlab程序清单(Mathematical Modeling Contest in 2010 in Jilin Province matlab Listing A Question)

for obtaining the period of a signal

说明：  实现运动模糊方向和运动模糊长度参数估计的方法。(estimation of motion blur parameters)

关于阵列天线的资料，适合初学者，不错的资料(Information about the array antenna, suitable for beginners, good information)

基于修正的hausdorff的图像匹配算法，可快速实现图像匹配(hausdorff mattch)

说明：  此为matlab教程范例，包括图像、小波分析、优化、神经网络、遗传算法及其他部分范例(This is an example of matlab tutorials, including images, wavelet analysis, optimization, neural networks, genetic algorithms and other parts of sample)

传感器系统的偏差估计方法，包括批处理最小二乘和递推最小二乘的实现代码。(The code realize the deviation estimation methods of the sensor system, including batch least squares and recursive least squares implementation.)

input: fun x(t) t min & t max a df T = t_max-t_min fs = a*1/T 输入1：方程，xt；输入2，3：信号起始时间；输入4：选取的采样周期是信号长度倒数的倍数， 默认为50；输入5：频域分辨率，默认为0.3 输出频域信号和频域范围 为了提高fft的速度，频域信号长度是2的次方( Input: fun x (t) t min & t max a df T = t_max-t_min fs = a* 1/T Input 1: Equation XT input 2,3: signal start time input 4: select the sampling period is the reciprocal multiples of the signal length, default is 50 input 5: frequency domain resolution, default is 0.3 of the output frequency domain signal and the frequency domain in order to improve the speed of the FFT, the frequency domain signal length is a power of 2)

Active filter and control strategies

QAM调制软比特解调，能够更准确进行解调。(Soft bit QAM modulation and demodulation, can be more accurately demodulated.)
