存在麦克风增益相位误差时候的宽带波束形成器设计,采用最小二乘方法来实现。 (Phase error exists when the microphone gain broadband beamformer design, using the least squares method to implement.)

对一个信号进行奇异值分解，根据差分谱最大值点，重构信号，达到降噪的目的。(Signal for a singular value decomposition, according to the differential spectrum maximum point, the reconstructed signal to achieve noise reduction purposes.)

通过对OFDM信号的CCDF曲线进行分析，得出了联合哈特莱变换和限幅算法降低OFDM信号峰均比的方法确实降低了OFDM信号的PAPR值(through the analysis of CCDF curve of OFDM signal, it is true to reduce the PAPR value of OFDM signal by use the method of the United Hart transform and clipping algorithm for PAPR reduction)

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)

包括针对调制识别的ASK,PSK,FSK,16QAM,以及hilbert变换的matlab源代码，注意是针对调制识别的(Including modulation recognition for ASK, PSK, FSK, 16QAM, and hilbert transform matlab source code, attention is directed modulation recognition)

利用MATLAB可视化图形界面编程，利用tab及panel控件实现多标签(Using MATLAB visual graphical interface programming, the use of tab and panel controls to achieve multiple tags)

我自己写的一级倒立摆的MATLAB仿真程序，用M语言的，值得一看的，是交给老师的大作业(I wrote it myself an inverted pendulum MATLAB simulation program, using M language, worth a visit is to the teacher)

OFDM多载波调制方式的DFT变换，以及OFDM波形的仿真(OFDM multi-carrier modulation of the DFT transform, and the OFDM waveform simulation)
