Matlab Filter Implementation
In this section, we will implement (in matlab) the simplest lowpass filter
$displaystyle y(n) = x(n) + x(n-1), n=1,2,ldots,N $
(from Eq.$ ,$(1.1)). For the simplest lowpass filter, we had two program listings:
Fig.1.3 listed simplp for filtering one block of data, and
Fig.1.4 listed a main program for testing simplp.
In matlab, there is a built-in function called filter3.3 which will implement simplp as a special case. The syntax is
y = filter (B, A, x)
where
x is the input signal (a vector of any length),
y is the output signal (returned equal in length to x),
A is a vector of filter feedback coefficients, and
B is a vector of filter feedforward coefficients.
The filter function performs the following iteration over the elements of x to implement any causal, finite-order, linear, time-invariant digital filter:3.4

越来越多的学科已发展到不得不分析非线性情况的地步。而matlab却还没有非线性分析工具箱。(The increasing number of disciplines have been developed to the point of having to analyze the nonlinear case. Matlab still has no nonlinear analysis toolbox.)

用BP网络逼近某曲线函数，在神经网络中邮广泛的应用 是系统辨识的基础。
通过反馈来不断的调整系数，限制了最大循环次数 防止进入死循环，当然如果想要得到更精确的系数可以增大循环次数。
(Using BP network function approximation to a curve, mail is widely used in neural network is the basis of system identification.
Through feedback to constantly adjusted factor, limit the maximum cycle times to prevent into dead circulation, and of course if you want to get a more accurate coefficients can increase the cycles.)

OFDM_Channel-estimation
OFDM(正交频率调制)实现多载波调制基本思想是将带宽信道分解成许多并行的窄子信道，是每个子信道的想干带宽，从而实现平稳衰落。搭建了完整的OFDM信道链路系统，运用三种不同的信道估计方法(LS信道估计、DFT信道估计、Improved-DFT信道估计)，并对AWGN理想信道和衰落信道误码情况进行了仿真和比较。(OFDM (Orthogonal Frequency Modulation) multicarrier modulation basic idea bandwidth channel is decomposed into a number of parallel narrow subchannels, each subchannel wanted bandwidth, in order to achieve a smooth fading. Build a complete OFDM channel link system, the use of three kinds of different channel estimated method (LS channel estimated, to the DFT letter Tao estimates, Improved-the DFT letter Road estimated), and AWGN ideal letter Road and fading channel bit error situation conducted a simulation and comparison .)

超高速OFDM系统传输模型 CP
在研究了超高速OFDM系统传输模型的基础上，对OFDM系统的传输信号结构进行了分析，结合传统的多普勒频移算法，用OFDM信号循环前缀所包含的相对频偏信息设计了实时性较好的多普勒频移估计方法，并分析了多径效应对于循环前缀数据的“污染”效应，对该算法进行了优化，提高了算法的频移估计性能，并对该算法进行了性能验证。(Based on the study ultra-high-speed transmission of OFDM system model, the OFDM signal structure for the transmission system is analyzed, combined with traditional Doppler shift method, the relative deviation OFDM signal with cyclic prefix information contained in the real-time design Doppler shift better estimation methods, and analyzes the " pollution" effect of multipath effects for cyclic prefix data, the algorithm has been optimized to improve the frequency estimation algorithm performance and the performance of the algorithm verification.)
