one of the best ways to have a blind channel estimation is using a precoding after before IDFT operation in OFDM systems,this simulation shows the precoding infulence on the system.

利用matlab进行动力学仿真之一，学习理论力学的同学可以参考一下(Matlab dynamics simulation carried out using one of the students to learn theoretical mechanics reference)

用于splitlab 的地震目录添加，数据请自行在USGS下载，详细说明见代码内部(used for the log add in splitlab)

例1 采用动量梯度下降算法训练 BP 网络。 例2 采用贝叶斯正则化算法提高 BP 网络的推广能力。在本例中，我们采用两种训练方法，即 L-M 优化算法（trainlm）和贝叶斯正则化算法（trainbr），用以训练 BP 网络，使其能够拟合某一附加有白噪声的正弦样本数据。(Example 1 uses the momentum gradient descent algorithm to train the BP network. Example 2 uses the Bayesian regularization algorithm to improve the generalization ability of BP network. In this example, we use two training methods, the LM optimization algorithm (trainlm) and the Bayesian regularization algorithm (trainbr), to train the BP network to fit a sine sample with white noise data. )

说明：  MATLAB的瑞利衰落信道仿真，针对服从瑞利分布的多径信道进行模拟仿真，加深对多径信道特性了解。(Channel Emulation of Rayleigh fading by using MatLab,which is aimed at the Multipath Propagation channel that obey Rayleigh distribution, so it could be furthered comprehension of characteristic on the Multipath Propagation channel.)

An estimation method for the inference on parameters of a dynamic macro model originally developed by Christiano, Eichenbaum and Evans is examined, extended and implemented in MATLAB.

memcached的C,c++实现，使用它可以方便的实现跨进程数据共享(memcached s C, c++ realize, it can be easily achieved using inter-process data sharing)

LMS算法函数 实现LMS算法定义，方便之后调用(least mean square algorithm)

【matlab编程代做】 在N维空间中的贝塞尔插值 可以作为参考使用学习 ([Do] matlab programming generation in N-dimensional space can be used as a reference to use Bezier interpolation learning)

最新的bellhop软件,用于信道建模，很好用的。(the newest bellhop software, it is used for modelling channel, and it is so useful)
