用matlab做的最小二乘法外推多项式拟合卫星周跳，可以学习。(Using matlab to do the least squares polynomial fitting extrapolation satellite cycle slips, you can learn.)

matlab code for air...air medium

Linear prediction follows naturally from the general mathematics of linear systems. As the system output is defined as a linear combination of past samples, the system’s future output can be predicted if the scaling coefficients bj and ak are known.

频域内低通滤波实现图像平滑，程序原代码来自书籍，《计算机图像处理与识别技术》，作者王耀南等(frequency low pass filter)

说明：  最基本的用MATLAB生成PID的程序 对初学者有用!!(Using MATLAB to generate the most basic procedures for PID useful for beginners!!)

针对双极性、单极性码产生直扩系统，并加上宽带噪声干扰，(For bipolar, unipolar codes have a direct expansion system, and with broadband noise,)

Script for computing the BER for BPSK modulation in a Rayleigh fading channel with equal gain combining

鲁棒自适应滤波器的MATLAB仿真和实现。这里采用的一种变步长的NLMS算法（VSSNLMS）(Robust adaptive filter MATLAB simulation and implementation. A variable-step NLMS algorithm (VSSNLMS) used here)

说明：  MATLAB实现的huffman编码，并附有详细的过程说明(MATLAB implementation of the huffman encoding, together with a detailed description of the process)

采用迭代最小二乘法，根据GPS星历中伪距、卫星位置速度等信息解算接收机位置。(GPS position calculation by Least Square method.)
