说明：  产生一个10000位的bipolar信号并画出bit error performance的模拟图像，求出BER(The source generates equally probable bits, P(0) = P(1) = 0.5. (a) Construct a program to generate 10000 bits with bipolar signaling. (b) Use your program to simulate the bit error performance of the system with Eb/N0 = 0, 2, 4, 6, 8, 10 dB. (c) Compare your simulated performance with the analytical expression for the bit error rate (BER):)

这个程序可以用来计算复杂网络中的介数，稍微修改就可以实现边介数和点介数的计算。(This program can be used to calculate the number of referrals of complex networks, a slight modification can calculate the number of edges and points referral referral number.)

费歇尔准则要求类间均值差异最大而类内的离差平方和最小。(Fischer guidelines require the mean difference between the class and the maximum and minimum sum of squares within the class.)

时频分析，窗宽对信号恢复的影响 以及差值分析(Time-frequency analysis, the impact of the window width and the difference signal recovery analysis)

采用声子晶体能带理论求解周期性结构振动特性，采用解析法编程，适合初学者学习参考(Wave propagation in periodic structures band-gap behaviours)

SAR成像，使用的是经典的距离多普勒算法，用c++形成矩阵，然后可以在matlab上看到图像(SAR imaging, using the classic distance Doppler algorithm using c++ form a matrix, then you can see an image in matlab)

orthogonal frequency division multiplexing

these codes used to implement OFDM transmitter and receiver with low out of band radiation. the number of subcarrier is flexible.
