this is matlab code for estimating the static linear system with Recursive Least Squre that is written by matlab 7.0. Here we want to estimate the below function: 1 - u^2 + 2*u^3 +u^5 +3*u^7 these are 2 files : without noise and with noise finally,there are plots for showing results.

LMS algorithm for adaptive filtering. Worth seeing.

本程序将一随机信号通过瑞利信道产生输出，并用Jakes方法产生单径的符合瑞利分布的复随机过程(This procedure will be a randomly generates an output signal through Rayleigh channel, and use Jakes method produces single-path Rayleigh distribution meet the complex stochastic process)

基于AWGN通道的4ASK关于ber的仿真(BER Performance of 4ASK in AWGN Channel we study how to use amplitude to carry more digital bits in one data symbol. We use the 4ASK to modulate the signals)

本DTW的语音识别算法是日本学者sakoe提出的，这种方法比itkura的要好，但本算法没使用到加权，方法简单了，以后再图改进(The DTW recognition algorithm is proposed by Japanese scholars sakoe, this method is better than itkura, but did not use this method to the weighted method is simple, and later plans to improve)

关于matlab解热传导问题的解法，简单实用。适合计算流体初学者使用，另附一些matlab实例(Matlab Antipyretic conduction on the question of method, simple and practical. Suitable for beginners to use computational fluid, followed by a number of examples matlab)

Audio filter for Matlab How is it working? 1) Take the current samples and some previous samples (which previously had been stored) for multiplied by a factor defined. 2) Take the output values in past moments and multiply by other factors. 3) Finally, all the results of all these multiplications are added, giving an outlet to the current moment.

说明：  lms 自适应算法的仿真源程序 基于最小均方算法的。(LMS filter in MATLAB based on a simple and very useful mehtod which is used to estimate gradient.)

自适应算法的仿真，能实现很好的适应过程,解决干扰的影响(Adaptive algorithm simulation, can achieve a good adaptation process to resolve interference)
