matlab code for STFT

2013年秋季 北京航空航天大学惯性导航第一次大作业，指北方位平台惯导系统解算(homework of inertial navigation of beihang university )

this code uses newtons method but in the form for function to solve non linear equations. use all the file available in the rar file to run the code.

计算循环平稳信号的3阶累积量，用于信号检测方面的,用在高阶谱估计中,很有用的函数 (Cyclostationary signals calculated 3-order cumulant for the area of signal detection, spectrum estimation in high-end, the very useful function)

流形学习 经典matlab图形界面 含八种算法(Manifold learning classical matlab graphical interface containing eight algorithms)

说明：  GMSK位同步的Gardner改进算法,是IEEE上很好的一篇文章(GMSK bit synchronization Gardner improved algorithm is very good IEEE on an article)

瑞利衰落信道（Rayleigh fading channel）是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。(Rayleigh fading channel (Rayleigh fading channel) is a radio signal propagation environment, the statistical model. The model assumed that after the signal through the wireless channel, the signal amplitude is random, that is, " fading" and subject to its Rayleigh distribution envelope.)

基于matlab 通过线性变换法进行图像增强处理，对一些对比度较差的图像处理效果明显，如所附图像(Image enhancement)

针对采用解码-转发(DF)协议的协作中继网络,提出了一种基于买者-卖者博弈的中继选择和功率分配策略,通过将用户建模为买者,可以以最大效用为标准选择最优中继和确定最佳的购买功率;将中继建模为卖者,可通过先市场后利润的功率价格调整策略获得最大的利润。(For the cooperative relay network using decode and forward (DF) protocol, a relay selection and power allocation strategy based on the buyer seller game is proposed. By modeling the user as a buyer, the optimal relay and the optimal purchasing power can be selected with maximum utility as the standard. The relay is modeled as a seller, and the profit can be achieved through the market after the first market. The power price adjustment strategy obtains the maximum profit.)
