说明：  非线性最小二乘优化问题以误差的平方和最小为准则来估计非线性静态模型参数的一种参数估计方法。设非线性系统的模型为y=f(x，θ)，常用于传感器参数设定。(64/5000 A parameter estimation method based on the minimum sum of squares of errors. Suppose that the model of the nonlinear system is y=f(x,), which is commonly used for sensor parameter setting.)

说明：  用matlab程序模拟实现cdma系统的整个过程。包括并串、串并转换，m序列的产生，直接扩频、解扩，qpsk的调制解调，载波调制解调等。(Matlab program is used to simulate the whole process of CDMA system. It includes parallel serial, serial parallel conversion, m-sequence generation, direct spread spectrum, despreading, QPSK modulation and demodulation, carrier modulation and demodulation, etc.)

说明：  在Matlab软件上实现Mersenne Twister随机数的生成，并对结果进行仿真。(In the Matlab software to achieve Mersenne Twister random number generation, and the results are to be simulated.)

说明：  数字信号处理的一些MATLAB源程序，均已经通过编译、仿真，请放心下载使用。(digital signal processing some of MATLAB source, we have already passed compiler, simulation, Please be assured download for use.)

此程序对BPSK调制、载波锁频跟踪进行仿真，主要目的是锁频环 (sintable(k+1)=sin(2*pi*k/2^10) costable(k+1)=cos(2*pi*k/2^10) )
