Matlab code for Strapdown navigation system alignment(Matlab code for Strapdown navigation system alignment.)

这是现代通信系统书上付的程序 包括了通信的方方面面 非常全面(This is a modern communication system, paid for the book procedures, including all aspects of communication is very comprehensive)

录制自己的一段语音，时间控制在15秒到30秒左右；利用wavread函数对自己的语音进行采样，记住采样频率。 （1）画出原始语音信号的时域波形，而后以1秒为间隔，求出每秒数据的功率谱。 （2）根据语音信号特点，分别设计FIR及IIR滤波器，分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波，画出滤波后时域波形。用sound函数回放语音信号。 （3）求出特征频段语音信号随时间变化的曲线（每间隔0.05秒求一次功率谱）。 (Record your own voice for some time (15 seconds to 30 seconds) use wavread function of the voice samples, remember the sampling frequency. (1) Draw the original speech signal in time domain waveform, and then to 1 second intervals, the data obtained power spectrum per second. (2) According to the voice signal characteristics, FIR and IIR filters were designed, namely to draw the amplitude and phase frequency characteristic curve. With the design of the filters on the signal filtering, to draw the filtered time-domain waveform. Playback with sound function of the speech signal. (3) Find the characteristic band speech signal curve over time (0.05 seconds intervals seeking a power spectrum.))

一个关于FSK的matlab编写的小程序，欢迎大家指正讨论(FSK s matlab on the preparation of small procedures, welcome to correct me to discuss)

用dspbuilder实现32阶FIR滤波器(Achieved with a 32-order FIR filter dspbuilder)

在优化问题中，用于求解下列形式非线性规划问题(In optimization problem, the following form for solving nonlinear programming problem)

This model is to determine the number of solar panels needed and the minimum battery capacity needed(in amps)and also for the required backup time

地震勘探方法中的数据处理格式，包括各种转换方法。(Method of seismic exploration data processing formats, including various conversion methods.)

fisher辨别分析方法的修改版，这是我们做掌纹识别的的时候自己修改后的程序，仅供参考哦完整源代码，已通过测试。 (fisher analysis to identify the modified version, which is the time to do their own palm printts to identify the revised procedures, only reference Oh complete source code, has been tested. )
