MatLab code for simulation of a 4PPM communication system.

对接收信号进行转化和功率谱分析。得到信号的统计特性，主要是噪声放面。(The received signal is transformed and the power spectrum analysis. Get the statistics of the signal, is mainly the noise area.)

This matlab code has a PCM siystem

实现能量检测仿真，由main函数进行能量检测，psk_2实现BPSK调制，pdsnr计算出理论值，最后由main给出理论与仿真之间的画图比较。(Achieve energy detection simulation, the main function of the energy detection, psk_2 achieve modulation BPSK, pdsnr calculate the theoretical value, and finally given by the main draw between theory and simulation comparison.)

Quadrature amplitude modulation (QAM) is both an analog and a digital modulation scheme. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme.

应用matlab程序，实现了对手写数字的识别，准确率非常高。(Matlab application procedures, to achieve the hand-written digit recognition, the accuracy rate is very high.)

一个运动员在用脚颠球，是一个动画程序，球员画的很一般(An athlete in their feet Dianqiu, is an animation program, the players draw very general)

The Support Ve ct or Machi ne So fa r we have used a reference as sumpt ion tha t there exists a linear classifier that has a larg e ge ometric margin, i.e., whose decision b oundar y is we ll separa ted from all the training images (e xamples). Such a larg e margin classifier seems like one we would like to use. C an’t we find it more directly? Yes, we can. The clas sifier is known as the Support Ve ctor M achine or SVM for short.
