精通MATLAB 是北航的张志用写的电子书 介绍了MATLAB6.5的使用 (Proficient in MATLAB was written by Zhang Beihang' s book describes the use of MATLAB6.5)

应用于扩频通信，关于PN码扩频，在matlab中的完整程序代码。(Applied to spread spectrum communication, spread spectrum on the PN code in matlab full program code.)

说明：  清华大学数学建模讲义,可以帮助大家更好的学习数学建模这种课程.(Tsinghua University, Mathematical Modeling handouts that can help us better learning mathematical modeling of such courses.)

Solves part b for three values of p: 0.1, 0.3, 0.5, and 0.8. To solve for other values of p, just change the numbers in the vector p below.

matlab中Toolbox中带有的模型预测工具箱，有是示例程序(matlab in the Toolbox Toolbox with a forecasting model, there is a sample program)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)
