非常好的函数程序,关于超宽带的,省了不少事情啊(very good function procedures for UWB, save a lot of things ah)

釆用一个二阶系统的模型代替真实系统，其差分方程表达式为： 将此系统在计算机上仿真，输入信号u(k) 是幅值为1 的PRBS 信号，噪声e(k) 是（0，1）的正态分布序列，它的方差是可以调整的。这个系统的输出釆样值z (k) 与u (k) 作为已知数据，采用最小二乘法估计这个系统的参数。 (Preclude the use of a second-order system model instead of the real system, the differential equation expression: this system on a computer simulation, the input signal u (k) is the amplitude of the PRBS signal, and the noise e (k) (0 , 1) the normal distribution of sequence, its variance can be adjusted. The output of this system the Bian samples z (k) and u (k) as known data, the method of least squares to estimate the parameters of this system.)

利用此matlab程序，可以读取gps文件(using matlab for read text of gps)

the upsample and down sample function rebuild as new code resamplex

单纯形法,单纯形法，求解线性规划问题的通用方法。单纯形是美国数学家G.B.丹齐克于1947年首先提出来的。(danchuncing)

说明：  基于MATLAB的遗传算法的源程序,有需要的可以参考下 (Genetic Algorithm Based on MATLAB source, there is a need to make reference to the next)

Used on cellular phones to filter out background noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop). Includes a tutorial on how to use statistics (correlation coefficient) to calculate the signal to noise ratio. Realtime implementation using Texas Instruments TMS320C5510 DSK and TMS320C6713 DSK. Code mostly in C, except where it would be too slow and assembly language is used.

老师给的关于最优估计的matlab程序，包括卡尔曼 无迹卡尔曼等等的demos 和相关的pdf学习文档(Optimal State Estimation)

电力电子电路matlab仿真程序，丰富实用，即学即会。(Matlab power electronic circuit simulation program, rich in practical, that will learn.)
