ofdm粗频偏估计程序，包含5个模块，基于PN序列的同步(ofdm coarse frequency offset estimation procedures, including the five modules)

说明：  里面包含两个matlab程序，分别是对除法和对开方算法（或者是电路工作原理）的模拟。压缩包里分别有这两个算法的详细描述，主要用于学习。(It contains two matlab programs, one for divide algorithm and the other for sqrt algorithm. The .rar file also include two instruction files for the two algorithms.)

Simulink all digital pll with fixed point

一个小小的knn-demo，先用knn 做分类器进行分类，再去验证正确率(A small knn-demo, first with knn Do classifier, go to verify that the correct rate)

this code can embedding a watermark in an image

有关DSP仿真的书记 有关DSP仿真的书记(Simulation on the DSP on the DSP simulation secretary secretary)

说明：  bpsk、qpsk、16qam、64qam的解调matlab算法(bpsk、qpsk、16qam、64qam demodulation)

仿射不变特征提取 多尺度自卷积方法。。。。。。。。。。。。。。。。。。。(The Multi-Scale Autoconvolution (MSA) method offers a novel way of approaching this problem. The method provides affine invariant features with only moderate computational complexity and does not require any other segmentation steps than background elimination.)

一般离散信道的迭代算法。信道能无错误传送的最大信息率。对于只有一个信源和一个信宿的单用户信道，它是一个数，单位是比特每秒或比特每符号。(Iterative algorithms are generally discrete channel. Channel can be transmitted without errors maximum information rate. For only one source and a sink of the single-user channel, it is a number, in units of bits per second or bit per symbol.)

采用matlab解微分方程，讲解比较详细，值得看看(Using matlab for solving differential equations, to explain in more detail, is worth a look)
