OFDM

对非线性方程，要求一定的精度，用matlab求解。(Nonlinear equations require a certain precision, using matlab to solve.)

一个比较老的水印程序 MATLAB写的 (Watermarking a relatively old procedure written in MATLAB)

这是一个讲解OFDM原理及实现的文档，文档最后附上了matlab的OFDM实现(This is an OFDM explain the principle and implementation of the document, the document was last attached matlab implementation of the OFDM)

在程序中用一般的MUSIC方法估计了信号的频谱，从两图中可看出在信号各频率处，频谱的峰值较大，故能明显的与噪声相区别，可在一定程度上避免在信号幅度较小时信号被噪声淹没的情况。(MUSIC method general procedures used to estimate the spectrum of the signal, it can be seen from the two graphs in the signal at each frequency of the spectrum peak larger, and it could be significantly distinguished from noise in the signal can be avoided to some extent a lesser extent, the signal is noise submerged.)

用MATLAB实现SAPSO、SecPSO、SecVibratPSO算法，程序没错误，可以直接运行，非常适合刚学PSO者(Implementation of SAPSO, SecPSO, SecVibratPSO algorithm with MATLAB, the program no error, can be directly run, very suitable for just learning PSO )

粒子滤波目标跟踪程序，地面雷达跟踪一个下落物体的弹道系数、速度和位置。(Particle filter target tracking procedures, ground radar tracking ballistic coefficient, velocity and position of a falling object.)
