说明：  二相相移键控（BPSK）是用二进制基带信号（0、1）对载波进行二相调制。BPSK是最简单的PSK形式，相移大小为 180°，又可称为2-PSK。在群点聚集的地方，其实都不是非常有关系，在该图像中，群点分布在水平轴上的0°和180°上。由于BPSK使用严重的失真致使解调器作出错误的判断，所以该调制方式是所有PSK中最强的。但它只能以1bit/symbol调制而不适合高数据率应用情况。 (bpsk modulation)

最优化方法及其Matlab程序设计，乘子法程序，非线性最小二乘问题源码，最速下降法与牛顿法源码等等(Optimization method and Matlab programming, multiplier method procedures, non-linear least squares problem source, the steepest descent method and Newton' s law code, etc.)

利用matlAB中自带的guide工具，绘制三维李萨如图形，也可绘制广义的李萨如图形，包括矩形波，三角波(the simulation of lissar figure)

这是改进的人工势场法可以用于机器人避障,希望对你的学习有所帮助(This is improved artificial potential field method can be used in robot obstacle avoidance)

由于利用fft变换存在频谱泄露和栅栏效应，本程序利用加窗fft算法，来解决这方面的问题(As the use of fft transform existing fence effect of spectrum leakage and the procedure used windowed fft algorithm to solve this problem)

Simulink 实现的FM调制，载波13KHz，频偏3KHz，调制波形存为一个波形文件。FM解调采样双斜率鉴频，解调直接输出到声卡。(Simulink implementation of the FM modulation, carrier 13KHz, offset 3KHz, modulation waveform file saved as a waveform. FM demodulation of two-slope Kam sampling frequency, demodulated output directly to the sound card.)

FIR filter with weight function

產生頻率選擇性衰落的雷利通道，參數由天線結構、OFDM系統的結構與功率延時結構來決定。(Have a frequency selective fading channel of Raleigh, parameters from the antenna structure, OFDM system, the structure and power structure to delay the decision.)

战术武器子惯性导航系统与机载主惯性导航系统的空中动基座传递对准(Tactical weapons sub-inertial navigation system and the airborne inertial navigation system air moving base transfer alignment)

实现基于贝叶斯阈值的小波图像去噪算法，相比较其它的小波去噪算法而言，去噪效果非常好。(Wavelet image denoising based on Bayesian threshold, compared with other wavelet denoising algorithm, the de-noising effect is very good.)
