利用容积卡尔曼滤波器写的一个滤波程序，完美运行(A filtering example that uses the cubature Kalman filter)

The statements below guide us to write the code for the transmission of sensed data to a sink node using cognitive radios in multiple spectrum bands. In doing this we are trying to find the most appropriate modulation scheme using MATLAB simulation.

展频PLL时钟（SSC）产生电路，可以产生三角波、正弦波或者单频载波(Delta_Sigma Modulator, to be used in TXPLL with SSC modulation. this program simulates the Spread spetrum clocking scheme. the SSC can be set to triangle wave or sinewave, or you can also set it to be constant frequency which without SSC. the relevant parameters is programmable. )

隐马尔可夫模型参数的极大似然估计,用来求解HMM的第三个问题(HMM maximum likelihood parameter estimates used to solve the third problem HMM)

面向对象的能描述光子晶体的结构有限元算法的工具箱。(Object-oriented structure of photonic crystals can be described in the finite element method of the toolbox.)

用来计算pdl的源程序，非常有用，使初学者的良好使用教材。(For at least 5 C or Java source code or other good For at least 5 C or Java source code or other good For at least 5 C or Java source code or other good)

根据所限定的条件，绘制出并联机构运动空间图(accoring the limit you need to choose the available degree combinations)

说明：  单极性RZ码，Rb=2Mb/s，默认k=14和设定Rt=0.5，功率谱密度和时域波形(Unipolar RZ code, Rb = 2Mb/s, the default settings k = 14 and Rt = 0.5, power spectral density and time-domain waveform)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

matlab源碼 可用來內差時間時程資料 例如原本時間間隔為0.01秒 內插生成0.001秒(matlab source code available to the time of the interpolation process data such as the original time interval of 0.01 seconds interpolation generated 0.001 seconds)
