用于产生CRC校验的matlab源码，生成多项式g(x) = x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1，按比特输入按字节输出(Matlab code for CRC-16 generation)

Código para simular un controlador PID

用matlab实现QPSK调制，各路信号的频谱，高斯白噪声信道(QPSK modulation to achieve with matlab, and the brightest signal of the spectrum, white Gaussian noise channel)

说明：  衰减曲线法实现PID参数整定 给出系统前向通道的传递函数，matlab计算PID参数(PID parameter tuning by attenuation curve method)

Kalman Filter : Simple simulink example

Matlab 编程所用 很好的一本书,如果你想学好Matlab的编程开发，这本书是一个不错的帮手，下载来看看吧。(This book is very useful for the people who want to learn Matlab well.)

This tutorial starts with a simple conceptual model of an analog Phase-Locked Loop (PLL). Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both ANSI C or synthesizable HDL). The step-wise elaboration of the model illustrates how Simulink® forms the basis a model-based design where continuous verification of the model reduces errors.

说明：  利用matlab实现了ofdm系统，从发送到接收，并可统计在不同信道下的系统性能(Achieved using matlab ofdm systems, from sender to receiver, and can channel statistics in different system performance)

Bernstein_chebyshev_Lagrange等基函数编写和实现(Bernstein_chebyshev_Lagrange basis functions, such as the preparation and implementation)

用粒子群算法PSO优化BP神经网络，改善预测精度(The BP neural network is optimized by particle swarm optimization (PSO) to improve the prediction accuracy)
