非线性回归通用程序,稍加修改即可用于各种非线性回归(General non-linear regression procedures, a little modification can be used for various non-linear regression)

码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统 （beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。(Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.)

Implementation algorithm to change contrast of an image

有限元 matlab 程序-----二维圆柱体的散射 (Finite element matlab program----- scattering of two-dimensional cylinder)

该程序利用空时二维自适应处理的原理，采用最优处理器的方法，对杂波矩阵进行处理，并能够绘制出二维杂波功率谱图，功率谱亮度图，特征谱图，二维频响图，以及最优化比较图(The program is the use of space-time two-dimensional adaptive processing principle, the optimal processor, clutter matrix processing, and be able to draw a two-dimensional clutter power spectrum, the brightness of the power spectrum diagram, characteristic spectra, two dimensional frequency response diagram, as well as the optimization Comparison)

Digital Communication Using Chaotic-Pulse-Position Modulation

fortran的matlab代码,可以将fortran仿真结果可视化(fortran matlab code, you can visualize simulation results fortran)

阈值变换，小波变换，从前人的基础上改进变换，使得信号噪声压制的很低。(Threshold transform, wavelet transform, improve the conversion of people on the basis of the past, so that the signal noise suppression is very low.)
