本程序利用matlab实现2维栅格地图建模，调试成功，有兴趣的可以下载(This procedure using matlab to achieve a two-dimensional grid map modeling, debugging success, interested can download)

简单的OFDM的均衡程序，采用的是ZF（迫零均衡），效果较好。(OFDM-equalization process simple, using the ZF (zero forcing equalizer) is better.)

自适应混沌粒子群算法的matlab程序，有测试函数(Adaptive chaotic particle swarm algorithm matlab procedures, test function)

关于线性调频信号，输出它的时域、幅度谱、相位谱(Linear FM signal, the output of its time-domain amplitude spectrum and phase spectrum)

说明：  改进的小波阈值去噪法，但是其中有点不对，不知道会不会对大家有用，想看的下哈(Improved wavelet threshold denoising method, but one a bit wrong, do not know will not be useful to everybody, want to see the next Ha)
