运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)

Particle filtering is an non-parameterized algorithm via sequential Monte Carlo simulation to actualize bayesian estimation. This paper expatiated the development and the research status of particle filtering at present.Then,introduces and analyses the principle of particle filtering、the existed key problems and countermeasures in detail.Furthermore,it sum up eleven improved methods of particle filtering algorithm.Meanwhile,applications are addressed in this paper.Finally ,the prospect of particle filtering is presented.

matlab需要那么复杂的多重积分,实在没办法才考虑使用.一般来说,积分中带有参数,无论是被积表达式或者说积分限都是相当麻烦的,求解消耗的时间非常多.............数值积分才是解决问题的通法,可以自己调节精度~(it is good. If you visited Indianapolis you would be able to find your way around easily because most of the streets corss each other like a chessboard(棋盘). In the center of the city, called the Circle, stands the Soldiers and Sailors’Monument, 100 Meters high. Also in the center there are many buildings made of the famous Indiana stone, which makes them white in color.)
