元胞自动机模拟走廊逃生的matlab程序，很好用(Cellular automata simulation corridor escape)

说明：  这是matlab编写的三个程序的代码以及最后结果，是综合实验时做的(This is three programs written in matlab code and the final result is to do comprehensive experiments)

汽车制动防抱死系统参数标定程序，用于分析汽车动力学特性，需要与carsim汽车仿真软件进行联合仿真，否则车辆模块出现badlink。(Automotive anti-lock braking system parameter calibration procedures for the analysis of vehicle dynamics, need with carsim automotive simulation software co-simulation, vehicle module badlink.)

对给定的正方矩阵进行Doolittle分解，并分析其计算量。(Doolittle given matrix decomposition)

Interpolation using Lagrange

瑞利衰落信道下的MIMO各态历经系统容量仿真(Rayleigh fading channels MIMO ergodic system capacity simulation)

激光散斑测量微流速，如果有散斑图，输入，给出相应的相对速度(find out the speed of laser speckle)

Implementation of an AVL tree using C. A data structure type.

图像dct变换，量化，f3隐写，压缩，解压，使用matlab实现(Image DCT transform, quantization, F3 steganography, compression, decompression, using MATLAB to achieve)

说明：  与连续信号的解调相比，短时突发信号持续时间短，不适用性能良好的反馈环路算法，需要使用前向幵环算法。与一般突发信号相比，短时突发信号没有训练序列、同步头等辅助信息，所有参数需要利用有限的数据估计。与合作通信相比，盲接收信号参数的初始偏差较大，估计范围小的算法不适用。每个突发包的数据有限，解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)
