块匹配运动各种算法 三步法，新三步法，四步法，钻石匹配法(block matching )

说明：  根据GPS软件接收机的基本原理编写的，卫星捕获到跟踪到解算的完整程序(GPS)

用jacks 方法产生瑞利衰落 需要的朋友下来看看资源互换(methods used jacks Rayleigh fading need to see friends from exchange resources)

这是一个关于全变分的盲复原算法，该算法在实际应用了取得了很好的效果，希望对大家有好处。(This is a variation on the whole of blind image restoration algorithm in the practical application of the good results obtained, we hope to benefit.)

本程序是经典谱估计方法的程序，仿照＜数字信号处理＞胡广书．包含了书中后面三章的所有方法．另外还有ＦＩＲ，ＩＩＲ数字滤波器的去噪方法，ＳＶＤ特征值去噪，信噪比的计算等等．是一经典的程序组．希望和所有人共享(this procedure is classic method of spectral estimation procedures, modeled on the "Digital Signal Processing" Mr Kwong book. The book contains three chapters behind all the way. Another FIR, IIR digital filter de-noising, SVD eigenvalue denoising, the signal-to-noise ratio calculation, and so on. Is a classic procedure group. All sharing hopes and)

组合导航和初始对准中都涉及到杆臂效应补偿（滤波方法）(Combination of navigation and the initial alignment of compensation related to the lever arm effect (filtering method))

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 (128 of an OFDM symbol of a valid symbol 128 inserted virtual sub-carrier Symbol rate (the effective data rate) fsymbol sending rate (including virtual subcarriers) 2fsymbol Of the input data needs to be 2 times the transmission data rate, in order to carry out the interpolation, to achieve the bit timing tracking, i.e. four times the sampling rate modulation signal fsymbol OFDM symbol Nfft = 128 points One OFDM symbol data points nfft* 2 = 256, the Guard Interval dot = Ng* 2 = 64)

ofdm仿真 其中包括qpsk调制解调，加高斯，串并转换等；最后有误码率曲线的输出(ofdm simulation including qpsk modulation and demodulation, plus Gaussian, string and conversion Finally there is an output bit error rate curve)
