说明：  循环码编码,能够根据用户需要改变参数，完成循环码编码(crc encode)

复杂网络的小世界模型动态行为的分析，近代复杂网络的开篇(the dynamic of small world network)

说明：  用迭代法进行阈值分割的源代码，可以实现，希望对大家有所帮助。(Iterative thresholding method source code, you can achieve, we want to help.)

新的简单的粒子群算法 ,可以用于算法优化，全局寻优(A new simple PSO Particle Swarm Optimization )

用双线性变换法设计IIR数字滤波器,程序，用图形显示(Bilinear transformation method of IIR digital filter design, procedures, graphical display)

直接序列扩频，信道采用重复编码，2psk调制，针对白噪声，多径环境下的误码率仿真(Direct sequence spread spectrum, channel coding using repeated, 2psk modulation, for white noise, BER simulation of multipath environments)

一个三角形单元的有限元程序简易算例，最后可用输出tecplot打开的云图文件.plt(A triangular element of the finite element program simple example, the last available output tecplot open cloud file .plt)

波束形成相关程序，包括窄带常规波束形成及MVDR波束形成的波束图和方位估计仿真，还有宽带小数时延常规波束形成器的仿真。本程序主要基于水声背景，模型是最简单的线列阵，但对其他阵型只要修改至相应方向相应向量即可，对雷达和语音阵列信号处理修改相应波速频率即可。(Beam forming procedures, including conventional narrowband beamforming and beamforming MVDR beam pattern and orientation estimation simulation, as well as conventional broadband fractional delay beamformer simulation. This program is mainly based on the background the sound of water, the model is the simplest linear array, but as long as the formation of other modifications to the corresponding direction vector corresponding to, radar array signal processing and voice modify the velocity frequency.)

The source code is a simulation of VERTICAL-BELL LABORATORIES LAYERED SPACE TIME (V-BLAST) with QAM (Quadrature Amplitude Modulation)
