Mackey-Glass prediction series

说明：  Scilab软件与MATLAB功能相似，而且它是一个开源项目。功能强大，使用方法不简单。本教材是学习此软件较详细的资料。(Scilab software with features similar to MATLAB, and it is an open source project. Powerful, simple to use. The materials to learn the software more detailed information.)

sound localization code using the matlab. this is a simulation file

基于pic18f452的温度显示程序，DS18B20-lcd1602.(Based on the pic18f452 temperature display program, DS18B20-LCD1602.)

永磁同步电动机直接转矩控制系统研究，内容新颖，浅显易懂(Permanent Magnet Synchronous Motor Direct Torque Control System, innovative, and easy to understand)

MATLAB中单位脉冲信号和单位抽样序列的产生程序(MATLAB in the sampling unit and unit pulse sequence generation program)

it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in this program multiuser CDMA system is used ,, spreading is done using HADAMARD matrix .. or WALSH code .. and BER vs SIGNAL to NOISE ratio graph is computed

this file gives the parameters of a model estimated from given data. this is usfull in estimationa and forecasting
