短时傅里叶变换函数，用以实现信号的短时傅里叶变换，观察时频图(Short-time Fourier transform functions to implement short-time Fourier transform signal, when observed frequency diagram)

主要对扩展卡尔曼滤波（EKF）、无迹卡尔曼滤波（UKF）及改进无迹卡尔曼滤波（MAUKF）算法进行研究，研究了三种算法的基本原理和各自的特点。其中扩展卡尔曼滤波器是将卡尔曼滤波器局部线性化，其算法简单，计算量小，适用于弱非线性、高斯环境。无迹卡尔曼滤波器是用一系列确定样本来逼近状态的后验概率密度。改进无迹卡尔曼滤波算法在UKF的基础上引入衰减因子。(Improved Kalman filtering algorithm)

这是我在做超宽带测距定位研究时，编写的一个matlab程序，非常值得大家参考。(This is what I was doing UWB Ranging positioning studies, preparation of a matlab program, very worthy of your consideration.)

说明：  一些基于CDMA的编码程序，希望对初学者有一定的帮助。(some CDMA-based coding process, and I hope to beginners helpful to a certain extent.)

A MIMO multiplexing system with NT transmit and NR = NT receive antennas is designed. The main challenge for MIMO systems lies in the non-orthogonality of the transmission channel. This can be solved by turbo processing. Turbo channel encoder is used for converting the bits in its suitable form. Then different M-ary QAM is compared.
