人们熟知的双谱（bispectrum），也就是三阶谱估计。具有一定的参考价值。(known as the bispectrum (bispectrum), which is third-order spectrum estimation. With some reference value.)

根据果蝇优化算法得到极速学习机隐层神经元的数目依据得到的隐层神经元数目和极限学习机的方法对训练样本和测试样本进行训练学习。(According to the fruit flies optimization algorithm to get extreme learning machine based on the number of hidden layer neurons of hidden layer neurons number and extreme learning machine method of training samples and testing samples to carry on the training study.)

东北大学研究生上课时数字图像处理课的课件(Northeastern University graduate class of digital image processing course courseware)

MATLAB编写的利用u律函数实现的抑制OFDM峰均比的程序，程序通过运行，通过u率函数对信号压扩后，PAR明显降低(U law written by MATLAB functions for OFDM PAPR suppression program, the program by running through the u signal compression and expansion rate after the function, PAR was significantly lower)

说明：  利用Matlab，建立了PFC电路的精确仿真模型，没有斜坡补偿。(matlab,PFC simulation)

这个程序是用SLM算法抑制峰均功率比的matlab仿真程序，对100000个OFDM符号进行统计然后表征算法对PAPR的改进程度，绝对可以运行(this process is inhibited by SLM algorithm PAPR of Matlab simulation program, to 100,000 OFDM symbols statistical algorithm then characterization of the degree of the improvement PAPR, absolutely can run)

信道估计 导频 MMSE 仿真 matlab (channel estimation simulation)

BBO算法的markov分析程序，是利用理论分析算法收敛性的不错代码(The BBO algorithm markov analysis program, theoretical analysis of the convergence of the algorithm good code)

点电荷电场与电势模拟程序(matlab语言)，对研究物理仿真的朋友会有帮助(Point charge electric field and electric potential simulation program (Matlab language), the friends of the physical simulation will be helpful)

1、根据干扰总功率要求，在PSK调制信号带宽内产生单音干扰和多音干扰信号，并叠加到产生的信号源上。 2、将收到干扰的信号进行频率搬移到基带，然后通过匹配滤波器以及解调过程得到信息，统计误码率并与真实信息的解调误码率进行对比，评估音频干扰对PSK信号的干扰效果。 (1, according to the total power requirement of interference generated tone signal interference and multi-tone interference in the PSK modulated signal bandwidth, and superimposed on the signal generated by the source. 2, the received interference signal to a baseband frequency shift, and the information obtained by the matched filter and a demodulation process, statistical error rate BER and the true information demodulation comparison, evaluation of the PSK signal, audio interference interference effects.)
