matlab实现GPS接收机中三阶锁相环跟踪环路 pll3

the thesis put forwards three detection methods.the thesis analyzes and compares them on voltage distortion effects, real-time character, application of use and complexity of algorithm , The thesis has done the real-time dynamic simulation using the MATLAB software ,which is based on three detection methods , and the results show the correctness of active filter scheme, and advantages and disadvantages of three detection methods.

某炮弹质量为20KG，直径120mm，出炮口是的初速为800m/s，初始发射角等于45°，试计算弹道。解答过程与程序详解(A shell quality is 20 kg, 120 mm in diameter, out of the muzzle velocity of 800 m/s, initial emission Angle is 45 °, try ballistic calculation. The solution process and procedure, rounding)

语音信号处理实基于MATLAB的语音信号时域特征分析 要求： 按所学相关语音处理得的知识，通过网上学习、资料查阅，自己设计程序，给出某一语音信号的短时过零率、短时能量、短时自相关特征的分析结果，并借助时域分析方法检测所分析语音信号的基音周期(yu yin xin hao chu li)

说明：  uwb进行脉冲位置调制,并且进行相关接收,画出其图形(UWB pulse position modulation, and the associated receiver, to give their graphics)

说明：  一个双隐层拟合非线性模型的例子，用matlab编写(A two hidden layer nonlinear model fitting example of the preparation with matlab)
